In the matter of the petition of 

BELL HELICOPTER TEXTRON 

CANADA LIMITED 

for an exemption from § 27.1 

ofTitle 14, Code of 

Federal Regulations 

Regulatory Docket No. FAA-2012-0123 

DENIAL OF EXEMPTION 

By letter dated January 16,2012, Mr. M. Peryea, VP BHTCL Engineering, Bell Helicopter 

Textron Canada Limited (Bell Canada), 12,800 rue de I' Aenir, Mirabel, Quebec, 171 IR4, 

Canada petitioned the Federal Aviation Administration (FAA) on behalf of Bell Canada for an 

exemption from § 27. 1 of Title 14, Code of Federal Regulations (14 CFR). The proposed 

exemption, if granted, would allow type certification of the Bell 429 model helicopter, with an 

increase in the maximum gross weight from 7,000 pounds to 7,500 pounds, as a normal category 

rotorcraft. 

The petitioner requests relief from the following regulation: 

14 CFR section 27.1 (a), as amended by Amendment 27-37, specifies, in pertinent part, that 

this part prescribes airworthiness standards for the issue of type certificates, and changes to 

those certificates, for normal category rotorcraft with maximum weights of 7,000 pounds or 

less. 

The petitioner supports its request with the following information: 

This section is a summary of the relevant information from the petitioner's request. 

The petitioner states that granting an exemption to Bell Canada would permit owners and 

operators of Bell 429 helicopters to carry more fuel or additional equipment, which would 

increase the level of safety of the Bell 429. The petitioner further states that the ability to 
2 

carry more fuel would afford operators opportunities for practical instrument flight rules 

(IFR) operations, avoiding the perceived necessity to fly in marginal visual meteorological 

conditions in order to meet operational commitments. 

The petitioner states that the Bell 429 is certified for single-pilot IFR (SPIFR) and includes a 

dual autopilot system in the basic aircraft design. The petitioner further states that the 

stability and control augmentation system function included in the autopilot provides inherent 

stability and facilitates better situational awareness. The petitioner adds that the autopilot can 

be coupled to the navigation functions to include the global positioning system (OPS) wide 

area augmentation system (WAAS) and with the W AAS approach feature, operators will be 

able to accomplish departures and approaches to previously unavailable landing sites such as 

hospital heliports or pre-arranged rural pick up points. 

The petitioner states that the Bell 429 is IFR certified and includes equipment that is in 

addition to the minimum equipment required under part 27. The petitioner adds that the Bell 

429 is certified for use with specialized equipment that can be added in order to minimize 

risks encountered for specific mission profiles. This includes a protected tail rotor system, 

traffic collision avoidance system (TeAS), certification for ditching, weather radar, and a 

supplemental type certificate (STC) for health and usage monitoring system equipment. The 

petitioner notes that other equipment that can be installed includes an enhanced ground 

proximity warning system (EGPWS), helicopter terrain awareness system (HT A WS) and an 

automatic deployable emergency locator transmitter. The petitioner further states that an 

additional weight capability will permit the addition of such equipment without the need to 

trade off equipment for payload/fuel. 

The petitioner states that the additional weight increase for the twin-engine Bell 429 SPIFR is 

628 pounds. This weight considers not just the engine weight but the additional structural 

requirements. In addition to the structure, there is a cascading weight increase associated 

with the category A installation. The additional structure requires more fuel to provide 

operationally suitable range. The additional fuel requires additional structure and the Bell 

429 must meet the crash resistant fuel tank design. Thus, the Bell 429 is penalized more than 

previous part 27 designs in meeting the new rules. 

The petitioner states that there is a positive impact both from new job creation and dollars 

into the economy. The petitioner estimates that 400 additional Bell jobs will be created and 

that 75 percent of those jobs will be in the United States. The petitioner estimates that Bell 

429 ship sales in the next five years will go from 150 to 500 ships and 150 million dollars in 

direct supplier sales will be generated to support production. The petitioner further estimates 

that an additional 1,600 indirect jobs will be created and long term spares and support would 

yield Bell and suppliers additional jobs and significant revenue on the order of 3.3 billion 

dollars over a nventy year period. 
3 

The petitioner states that an additional maximum weight capability would minimize 

operational risks for all Bell 429 operators. The petitioner further states that currently, the 

Bell 429 at 3, 125 kg (7,000 Ibs) is not capable of carrying a full load of fuel with 8 occupants 

(the maximum number of occupants certified for the Bell 429) and for operations the amount 

of fuel carried is calculated to meet the mission requirements to maximize payload available 

for passengers. The petitioner states that with additional weight capability, the Bell 429 

would have the ability to carry more fuel and hence provide for greater fuel margin for 

missions, resulting in an increased level of safety and benefit to the public. 

The petitioner states specific types of operations that utilize the Bell 429 such as helicopter 

air ambulance; oil and gas exploration, production and support; public safety operations; and 

utility and the public benefits that are deri ved from such operations. These benefits of greater 

weight capability, noted by the petitioner, for these types operations can be summarized as 

enhancing the operational mission capability of the Bell 429 by improving operational safety 

and efficiency and by increasing payload and range capability. The petitioner contends that 

the benefits associated with enhancing the operational mission capability of the Bell 429 will 

be realized by the public. 

In concluding, the petitioner reemphasizes that the more appropriate certification focus for 

part 27 rotorcraft should be on technical complexity and safety. The petitioner further 

emphasizes that the safety level of the Bell 429, based on current designs, is a significant 

improvement and in some cases exceeds the design level of current part 29 rotorcraft. 

Summary of Comments Received: 

A summary of the petition was published in the Federal Register on March 6, 2012 

(77 FR 13385). Numerous comments were received. The majority of the commenters were Bell 

429 operators or those associated with the product and are in favor of the exemption. Among the 

commenters opposed to the exemption were other rotorcraft manufacturers, a foreign part 29 

rotorcraft producer, and the European Aviation Safety Agency (EASA). 

This section is a summary of the relevant information from the comments received in the federal 

docket management system. 

Many of the commenters in favor of granting the exemption point to the Bell 429's design 

and performance capabilities to operate at the 7,500 pounds maximum gross we ight (MOW). 

Some of these commenters believe the aircraft has exemplary performance, especially in hot 

climates and high elevations, and is not meeting its full mission potential and marketability 

because of the 7,000 pound MOW limit. Some conunenters also believe that the Bell 429 

airframe, avionics, and certain safety features exceed or are comparable to other part 29 

rotorcraft currently in use. 
4 

Other commenters in favor of granting the exemption pointed to the expanded mission or 

operational opportunities and increased safety margins for the Bell 429 the additional 500 

pounds of allowed weight would provide. This includes, the capability to operate under both 

visual flight rules and [FR, carry extra mission equipment and additional passengers 

(operational or patient). and carry additional fuel for longer range flights (e.g., to service 

additional areas), extended on-site loitering, and reduced en route refueling during missions 

(for example, emergency medical services, law enforcement, utility and gulf oil platform 

transport). A com.menter also stated that added onboard fuel also reduces costs of enroute 

refueling and noise abatement at airports used for remotely managed fuel cache sites. 

Another commenter believes the current weight restriction directly compromises the quality 

of patient care. A congressional commenter encouraged the approval of the weight increase 

to increase service capability in a safe and cost effective way, and to serve his state's 

constituents through air ambulance and emergency medical service providers. 

Another commenter was in favor of the exemption since it provides the ability to install 

additional flight safety equipment in the Bell 429, such as, HTA WS, twin engine full 

authority digital engine controls, latest glass cockpit technology, dual automatic flight control 

system, radio altimeter, OPS supported W AAS, night vision goggles, wire strike protection 

system, cockpit voice recording and flight data recorder system, etc. Some commenters also 

recommended the FAA require installation of the equipment contained in the similar 

exemption granted by Transport Canada Civi l Aviation (TCCA). 

There were additional comments for the need to consider increasing the weight limit for part 

27 rotorcraft above the current 7,000 MOW, partially because of the technological advances 

in this category of rotorcraft. 

Comments in opposition to the exemption stated that Bell Canada did not provide sufficient 

evidence to support their claim that this exemption, if granted, would be in the public's 

interest. 

Also, from the opposing comments, there was an argument that approving this exemption 

would favor one company and provide a special favor by the FAA to this one manufacturer, 

resulting in unfair competition by benefiting economically the one manufacturer (Bell 

Canada). 

Some opposing commenters argued that approving the exemption is contrary to the public 

interest, is an attack on the current FAA and EASA harmonized type certification and 

airworthiness standards, implying a lower level of safety for a part 27 product, would 

undermine the integrity and fairness of the airworthiness standards of part 27 certification and 

safety protections, and would create a terrible precedent for the FAA. There was an added 

comment that this exemption would also compromise the safety objectives of distinct 

airworthiness standards between parts 27 and 29. 
5 

In opposing the petition for exemption, there was an argument that it was Bell Canada's 

decision to certify the Bell 429 model under part 27 rather than part 29. Also, that a grant of 

this petition for exemption would be tantamount to Bell Canada obtaining a benefit of 

transport category certification without the added cost of meeting the more stringent part 29 

airworthiness standards. 

A commenter also suggested that if the FAA wanted to consider a generally applicable 

change in the part 27 rotorcraft maximum weight limit, there should be a working group 

convened comprised of representatives from industry and other major national airworthiness 

authorities. 

In addition to comments received during the public comment period, a comment was 

received shortly after the close of the conunent period, well before deliberations on the 

petition's merits, commenter submissions, and the FAA's decision. This submittal, which 

has been placed in the docket, did not affect the FAA decision in this matter, or alter any of 

the discussions that appear in this document. 

The FAA's response to the commenters summarized points above: 

We agree that the installation of certain equipment that has already been FAA approved and 

other equipment that Bell Canada proposes to have approved may increase the operational 

level of safety of the Bell 429. However, other normal category rotorcraft similar to the Bell 

429 have been configured for helicopter emergency medical services, offshore, law 

enforcement, and other operations with similar safety enhancing equipment approved that did 

not require an exemption to increase the MOW beyond the 7,000 pound maximum weight 

limit. While the advantages of the additional equipment may increase the level of safety. the 

support for the increase in gross weight of the aircraft appears to primarily be for economic 

reasons, thus the perceived benefit to the public. 

Further, the fundamental philosophy in the evolution of the FAA airworthiness standards is a 

continued enhancement in safety with an accepted different level of safety based on gross 

weight. Currently, rotorcraft that exceed 7,000 pounds MOW are expected to meet the higher 

levels of safety prescribed by Part 29, transport category rotorcraft. To allow a rotorcraft to 

be certified at a higher weight than allowed by the regulations undermines the very 

philosophy that has served the United States aviation community since the beginning. 

Conunents did not indicate that the community at large believes the 7000 lb limit is 

inappropriate. However, the FAA will issue a notice in the future to seek public input on this 

topic. 

We agree that the operational capability of the Bell 429 could be enhanced with an increase 

in MOW. However, that is true for any normal category helicopter. Further, there are other 

normal category helicopters currently available in the market that can achieve similar 
6 

operational capabilities proposed by Bell Canada that did not require an exemption for 

increased gross weight. 

While we appreciate the corrunenter submissions, the comments have not provided sufficient 

rational to support the overall safety benefit o/the exemption requested. Nor have the 

commenters' submissions demonstrated that a grant of the relief sought would provide a level 

of safety at least equal to that provided by the rules from which exemption is sought 

(compliance with part 29 transport category rotorcraft airworthiness standards). 

Any change to the current philosophy of rOlorcraft airworthiness standards needs to be done 

in a public forum. Therefore, the FAA will issue a notice in the future to seek public input on 

the appropriateness of 7000 lb as the current MGW of Part 27. Additionally. we will seek 

public input as to whether there are more appropriate certification focus areas, such as 

"technical complexity and safety" as suggested by Bell Canada. 

The FAA's analysis is as follows: 

The type certification standards for nonnal category rotorcraft in 14 CFR part 27 are "minimum" 

standards. While the FAA agrees that the level of safety may be enhanced by the approved 

installation of additional certified equipment in the Bell 429, the FAA does not agree that this 

can or should be accomplished through the grant ofa blanket exemption from the applicability of 

part 29 for a rotorcraft weighing more than 7,000 pounds. 

An increase in MGW could allow Bell 429 operators to improve their operational capabilities 

primarily benefining those operators and their customers. This would present Bell Canada, Bell 

429 operators, and their customers with an economic advantage over their part 27 competitors 

since their competitors are limited to a 7,000 pound MGW. Comparable helicopters at a simi lar 

weight class that are part 29 certified would also be at a disadvantage since they were required to 

meet more costly part 29 certification requirements. Further, there are other nonnal category 

helicopters currently available in the market that can achieve similar operational capabilities 

proposed by Bell Canada that did not require an exemption for increased gross weight. 

Obtaining category A approval for the Bell 429 was strictly a Bell Canada business decision. 

This decision enhances the marketability of the Bell 429 when compared to non·category A 

helicopters. 

The additional safety enhancing equipment offered as part of the basic Bell 429 helicopter or as 

optional equipment was a Bell Canada business decision to allow the Bell 429 to be a 

competitive aircraft in the market place. Much of the operational safety enhancing equipment 

identified in the petition is common in respect to what is already installed and in use by other part 

27 helicopters (e.g., radar altimeter. TeAS, wire strike protection, EGPWSIHTAWS, and 

weather radar). 
7 

We agree that jobs in the United States could be created with the sale of more than 300 new 

helicopters. If there is a demand for that many helicopters, then helicopter manufacturers will fill 

that need. Like Bell Canada, most of the non-domestic manufacturers also have facilities in the 

US. Therefore, we believe that jobs will be added regardless of the manufacturer if there are 

additional helicopter sales as suggested by the petitioner. However, it is important to remember 

that a decision to exempt an applicant from FAA safety standards is, and should remain, 

primarily a safety decision. 

The FAA acknowledges that granting an exemption from § 27. 1 would probably increase the 

potential usefulness of the Bell 429, to the current operators. However, we anticipate that there 

will be very minimal economic benefit to the overall public if the petition for exemption is 

granted. We anticipate that most of the economic benefits will be realized only by Bell Canada, 

Bell 429 operators, and their customers. 

It is currently possible for Bell 429 operators to seek and obtain approval for installation of 

additional equipment, if the mission dictates. This could necessitate the removal of some 

equipment to comply with the part 27 weight limitation. Other nonnal category helicopters 

accommodate similar type equipment. The availability of these other part 27 helicopters remains 

an option for operators. While realizing that not granting the relief sought could have an 

economic impact on existing Bell 429 owners and operators, for the reasons stated above, we do 

not see the overall public benefit to the entire community. 

The certification procedures for aeronautical products and parts together with the airworthiness 

standards in the 14 CFR (Federal Aviation Regul ations) are intended to establ ish varying levels 

of safety for different aeronautical products. As these regulations developed over time, the FAA 

has based the distinction between nonnal and transport category rotorcraft certification 

requirements, in part, on the maximum certified gross weight of the aircraft. The gross we ight of 

aircraft provided a meaningful indication of the number of people and the amount of cargo likely 

to be carried, as well as the design complexity and perfonnance capabilities of the aircraft. At 

each stage of the incremental adoption of the airworthiness standards in 14 CFR parts 27 and 29, 

the FAA met the procedural and legal burdens of establishing a compelling safety rationale for 

each additional safety requirement. Parts 27 and 29 each establish an appropriate minimum level 

of safety for the design of nonnal and transport category rotorcraft, respectively. The effect of 

granting Bell Canada's petition would be tantamount to a de facto rulemaking action to amend 

part 27 by increasing its applicability weight. In addition, the effect of a grant would be 

tantamount to exempting the Bell 429 from the application of part 29. 

The FAA has received a number of petitions for exemption to increase the gross weight of 

specific helicopters to exceed the weight limitation of § 27.1. Typically, the FAA has denied 

these requests. The FAA has only granted exemptions to § 27.1 in one situation, directly related 

to rulemaking that increased the weight limitation for all part 27 helicopters. In 1995, the FAA 

established an Aviation Rulemaking Advisory Committee (ARAC) effort to recommend new or 

revised requirements for increasing the gross weight and passenger limitations for nonnal 
8 

category rotorcraft. This ARAC included representatives from the FAA, Joint Aviation 

Authorities, and TCCA as well as US and European heli copter manufacturers. 

This ARAC agreed that a gross weight limitation increase of part 27 to 7,000 pounds was 

appropriate. This was primarily because the evolution of the rotorcraft design standards 

(including the implementation of new crash worthiness regulatory requirements intended to 

improve occupant survivability in the event of a crash) had dri ven an increase to the gross weight 

of modem day part 27 helicopters and impacted the entire helicopter community. In conjunction 

with this increase, the ARAC agreed to certain increased design standards for part 27. Shortly 

after the ARAC recommendations were accepted by the FAA, but prior to final rulemaking, the 

FAA granted three exemptions to allow an increase in gross weight to specific helicopters. In all 

three cases, the FAA imposed all of the newly proposed rules, including the enhanced 

crashworthiness regulatory requirements. 

The only other similar part 27 petition for gross weight increase was received in 2007. After 

reviewing the reasons for that request, the FAA found the request did not differ materially from 

previously denied requests. The FAA denied that request without public input because the denial 

was not precedent setting. Similarly, this petition for exemption does not differ materially from 

previously denied requests. 

The argument made by the petitioner that an increase in gross weight for the Bell 429 is needed 

to accommodate the installation of safety enhancing equipment is not valid justification. An 

increase in gross weight for any nonnal category helicopter would accommodate the installation 

of additional safety enhancing equipment. 

Designation of applicable type design airworthiness standards affect more than a product's level 

of safety. Under part 2 1 type certification procedures, the first step in establishing the 

certification basis for a rotorcraft is to refer to the rotorcraft's MOW. An early design 

consideration for a rotorcraft type certificate applicant is whether to design for compliance with 

part 27 or part 29. The development and manufacturing costs and market viability ofa rotorcraft 

hinge largely on its type certification basis. The appli cability sections in parts 27 and 29 create a 

level playing field for rotorcraft designers so that from an engineering, investment and marketing 

perspective, all applicants work to the same regulatory expectations. The exemption relief 

sought for the Bell 429 would, if granted, place the BeJI429 at a competitive advantage to other 

rotorcraft over 7,000 pounds already required to meet part 29. Said diffe rently, the relief sought 

would, if granted. put existing part 29 rotorcraft manufacturers at a competitive disadvantage 

owing to the greater costs to certify and produce their products. 

As indicated previously, the FAA will issue a notice in the future to seek publi c input to 

detennine if7000 Ibs is the correct MOW for part 27. Further, we will seek to detennine if the 

current parameters (i.e., maximum weight and number of passenger seats) are the appropriate 

ones for the future. or if any other criteria may be more meaningful to establish the safety targets 
9 

for the rotorcraft airworthiness standards. We will also welcome entirely new ideas and 

concepts, if those are supported by the rotorcraft community consensus. 

The FAA's Decision: 

[n consideration of the foregoing and the fact that this petition does not differ materially from 

other petitions that have been denied in the past, the FAA finds that a grant of exemption would 

not be in the public interest. Therefore, pursuant to the authority contained in 49 U.S.C. 

§§ 40113 and 4470 I, delegated to me by the Administrator, the petition of Bell Helicopter 

Textron Canada Limited for an exemption from 14 eFR § 27.1 is hereby denied. 

Issued in Fort Worth, Texas, on August 13, 2012.
