Background 

Transport Canada, which is the 

aviation authority for Canada, has 

issued Canadian AD CF–2019–08, dated 

March 5, 2019 (Canadian AD CF–2019– 

08), to correct an unsafe condition for 

Bell Helicopter Textron Canada Limited 

Model 505 helicopters serial numbers 

65011 and subsequent. Transport 

Canada advises of the need to reduce 

the altitude limitations for Jet B and JP– 

4 wide-cut fuels following 

unsatisfactory performance of the 

engine at the original higher altitude 

limitations with these wide-cut fuels. 

This condition, if not addressed, could 

result in low fuel pressure, engine 

flame-out, or engine power interruption 

(a change in any engine performance 

parameter—including but not limited to 

gas generator speed, power turbine 

speed, main gas temperature, or output 

torque—outside its normal limits for the 

prevailing operating conditions). 

Accordingly, Canadian AD CF–2019– 

08 requires revising the RFM to reflect 

the reduced altitude operating 

limitations for Jet B and JP–4 wide-cut 

fuels. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Canada and 

are approved for operation in the United 

States. Pursuant to the FAA’s bilateral 

agreement with Canada, Transport 

Canada, its technical representative, has 

notified the FAA of the unsafe condition 

described in its AD. The FAA is 

proposing this AD after evaluating all 

known relevant information and 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other helicopters of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Figure 1–6. Fuel 

Operating Envelope (Sheet 1 of 1), of 

Bell 505 Rotorcraft Flight Manual BHT– 

505–FM–1, Revision 3, dated July 25, 

2018, which specifies limitations, 

normal and emergency procedures, 

performance data, weight and balance 

information, and provides a list of 

approved optional equipment 

supplements. This revision of the 

service information includes an updated 

figure of the fuel operating envelope 

showing the reduced pressure altitude 

limitations for Jet B and JP–4 fuels. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

revising the existing RFM for your 

helicopter by updating the fuel 

operating envelope figure to require 

reduced pressure altitude limitations for 

Jet B and JP–4 fuels. Incorporating the 

RFM revision may be performed by the 

owner/operator (pilot) holding at least a 

private pilot certificate and must be 

entered into the aircraft records showing 

compliance with this AD in accordance 

with 14 CFR 43.9(a)(1) through (4) and 

14 CFR 91.417(a)(2)(v). The record must 

be maintained as required by 14 CFR 

91.417, 121.380, or 135.439. This is an 

exception to our standard maintenance 

regulations. 

Differences Between This Proposed AD 

and the Transport Canada AD 

Canadian AD CF–2019–08 requires 

updating the RFM to Bell 505 RFM 

BHT–505–FM–1 Revision 3 or later 

revisions approved by Transport 

Canada, whereas this proposed AD 

would require revising the Limitations 

Section of the RFM for your helicopter 

by replacing the existing Figure 1–6. 

with Figure 1–6. Fuel Operating 

Envelope (Sheet 1 of 1) of Bell 505 RFM 

BHT–505–FM–1, Revision 3, dated July 

25, 2018. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 73 

helicopters of U.S. Registry. Labor rates 

are estimated at $85 per work-hour. 

Based on these numbers, the FAA 

estimates the following costs to comply 

with this proposed AD. 

Revising the existing RFM for your 

helicopter would take about 0.5 workhour for an estimated cost of $43 per 

helicopter or $3,139 for the U.S. fleet. 

Federal Register / Vol. 86, No. 179 / Monday, September 20, 2021 / Proposed Rules 52111 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed, I certify 

this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

Bell Textron Canada Limited (Type 

Certificate Previously Held by Bell 

Helicopter Textron Canada Limited): 

Docket No. FAA–2021–0783; Project 

Identifier 2019–SW–009–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by November 4, 

2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Bell Helicopter Textron 

Canada Limited (type certificate previously 

held by Bell Helicopter Textron Canada 

Limited) Model 505 helicopters having serial 

number 65011 and subsequent, certificated in 

any category. 

(d) Subject 

Joint Aircraft Service Component (JASC) 

Code: 7300, Engine fuel and control. 

(e) Unsafe Condition 

This AD was prompted by the 

determination that reducing the pressure 

altitude limitations for certain fuel types is 

necessary. The FAA is issuing this AD to 

address unsatisfactory flight performance of 

the engine above pressure altitude limitations 

for Jet B and JP–4 fuels. The unsafe 

condition, if not addressed, could result in 

low fuel pressure, engine flame-out, or 

engine power interruption. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Within 30 calendar days after the effective 

date of this AD, revise the Limitations 

Section of the existing Rotorcraft Flight 

Manual (RFM) for your helicopter by 

replacing Figure 1–6. with Figure 1–6. Fuel 

Operating Envelope (Sheet 1 of 1) of Bell 505 

Rotorcraft Flight Manual BHT–505–FM–1, 

Revision 3, dated July 25, 2018 (BHT–505– 

FM–1 Revision 3). Using a different 

document with information identical to that 

in Figure 1–6. Fuel Operating Envelope 

(Sheet 1 of 1) of BHT–505–FM–1 Revision 3 

is acceptable for compliance with the 

requirements of this AD. The action required 

by this paragraph may be performed by the 

owner/operator (pilot) holding at least a 

private pilot certificate and must be entered 

into the aircraft records showing compliance 

with this AD in accordance with 14 CFR 

43.9(a)(1) through (4) and 14 CFR 

91.417(a)(2)(v). The record must be 

maintained as required by 14 CFR 91.417, 

121.380, or 135.439. 

(h) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, International Validation 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. In 

accordance with 14 CFR 39.19, send your
