disaster. Only those survivors located in 

the declared disaster area are eligible to 

apply for SBA disaster loans. When the 

President declares a major disaster, the 

Federal Emergency Management Agency 

defines the disaster area. In major 

disasters, economic injury disaster loans 

and IDAP loans may be made for 

survivors in contiguous counties or 

other political subdivisions, provided, 

however that with respect to major 

disasters which authorize public 

assistance only, SBA shall not make 

economic injury disaster or IDAP loans 

in counties contiguous to the disaster 

area. Except for rural disaster 

declarations (as defined in § 123.3), 

disaster declarations issued by SBA 

include contiguous counties for both 

physical, economic injury and, in some 

cases IDAP assistance. Rural disaster 

declarations do not include assistance 

for contiguous counties. Contiguous 

counties or other political subdivisions 

are those land areas which abut the land 

area of the declared disaster area 

without geographic separation other 

than by a minor body of water, not to 

exceed five miles between the land 

areas of such counties. The individual 

islands of geographically isolated island 

chains, including Hawai’i, the U.S. 

Virgin Islands, and the Commonwealth 

of the Northern Mariana Islands, are 

also designated as contiguous to each 

other. When SBA issues an economic 

injury disaster declaration in response 

to a determination of an emergency 

involving Federal primary responsibility 

by the President, the disaster area shall 

include each State or subdivision 

thereof (including counties) included in 

the President’s emergency 

determination.

Background 

On November 16, 2021, P&WC 

applied for a type certificate for its new 

Model PW220A engine. The Model 

PW220A engine is a new centerline freeturbine turboshaft engine design 

intended to be used on transport 

category twin-engine helicopters. The 

engine architecture is a split 

compression system that incorporates 

the latest generation design 

methodology of a high-pressure ratio 

compressor, providing significant 

improvements in specific fuel 

consumption (SFC) and power. 

A single low pressure compressor 

(LPC) is driven by a two-stage uncooled 

power turbine, which also provides 

mechanical power through an output 

shaft to the helicopter rotor system. The 

high pressure compressor (HPC) is a 

two-stage compressor system driven by 

a single-stage cooled high pressure 

turbine (HPT). 

Type Certification Basis 

Under the provisions of 14 CFR 21.17, 

P&WC must show that the Model 

PW220A engine meets the applicable 

provisions of part 33, dated February 1, 

1965, as amended by amendments 33– 

1 through 33–34. 

If the Administrator finds that the 

applicable airworthiness regulations 

(e.g., 14 CFR part 33) do not contain 

adequate or appropriate safety standards 

for the P&WC Model PW220A engine 

because of a novel or unusual design 

feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the type certificate 

for that model be amended later to 

include any other model that 

incorporates the same novel or unusual 

design feature, these special conditions 

would also apply to the other model 

under § 21.101. 

The FAA issues special conditions, as 

defined in § 11.19, in accordance with 

§ 11.38, and they become part of the 

type certification basis under 

§ 21.17(a)(2). 

Novel or Unusual Design Feature 

The P&WC Model PW220A engine 

will incorporate the following novel or 

unusual design feature: 

A 30-minute all engine operating 

(AEO) power rating. 

Discussion 

The type certification basis for the 

Model PW220A engine does not contain 

adequate or appropriate airworthiness 

standards to address a 30-minute AEO 

power rating. Therefore, special 

conditions are necessary to provide 

additional requirements for rating 

definition, instructions for continued 

airworthiness (ICA), and endurance 

testing. 

The 30-minute time limit applies to 

each instance the rating is used; 

however, there is no limit to the number 

of times the rating can be used during 

any one flight, and there is no 

cumulative time limitation. The ICA 

requirement in these special conditions 

is intended to address the unknown 

nature of actual usage of the 30-minute 

AEO power rating and any associated 

engine deterioration. The applicant is 

expected to make an assessment of the 

expected usage and publish ICA’s and 

airworthiness limitations section (ALS) 

limits in accordance with those 

assumptions, such that engine 

deterioration is not excessive. The 

endurance test requirement of 25 hours 

of operation at a 30-minute AEO rating 

is similar to several special conditions 

issued over the past 20 years addressing 

the same subject. Because the PWC 

Model PW220A turboshaft engine has a 

continuous one engine inoperative (OEI) 

rating and limits equal to or higher than 

the 30-minute AEO rating, the test time 

performed at the continuous OEI rating 

may be credited toward the 25-hour 

requirement. However, test time spent at 

other rating elements of the § 33.87 

endurance test, such as takeoff or other 

OEI ratings (that may be equal to or 

higher values), may not be counted 

toward the 25 hours of required 

running. These special conditions 

contain the additional safety standards 

that the Administrator considers 

necessary to establish a level of safety 

equivalent to that established by the 

existing airworthiness standards. 

Applicability 

As discussed above, these special 

conditions are applicable to the P&WC 

Model PW220A engine. Should PW&C 

apply at a later date for a change to the 

type certificate to include another 

model incorporating the same novel or 

unusual design feature, these special 

conditions would apply to that model as 

well. 

Conclusion 

This action affects only a certain 

novel or unusual design feature on one 

engine model. It is not a rule of general 

applicability.

44701, 44702, and 44704. 

The Special Conditions 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the following special 

conditions are issued as part of the type 

certification basis for the Pratt and 

Whitney Canada Model PW220A 

engine. 

In addition to the general definitions 

in 14 CFR 1.1, the following definition 

applies to these special conditions: 

‘‘Rated 30-Minute All Engine Operating 

(AEO) Power,’’ means the approved 

shaft horsepower developed under static 

conditions at the specified altitude and 

temperature, and within the operating 

limitations established under part 33, 

and limited in use to periods not 

exceeding 30-minutes each. 

In addition to the airworthiness 

standards in part 33, the following 

special conditions apply: 

(a) Sections 33.1 Applicability and 

33.3 General: As applicable, all 

documentation, testing, and analysis 

required to comply with the part 33 

certification basis, must account for the 

30-minute AEO rating, limits, and 

usage. 

(b) Section 33.4, Instructions for 

Continued Airworthiness (ICA). In 

addition to the requirements of § 33.4, 

the ICA must: 

(1) Include instructions to ensure that 

in-service engine deterioration due to 

rated 30-minute AEO power usage will 

not be excessive, meaning that all other 

approved ratings are available within 

associated limits and assumed usage, for 

successive flights; and that deterioration 

will not exceed that assumed for 

declaring a time between overhaul 

(TBO) period. 

(i) The applicant must validate the 

adequacy of the maintenance actions 

required under paragraph (b)(1) above.

(2) Include in the airworthiness 

limitations section (ALS), any 

mandatory inspections and 

serviceability limits related to the use of 

the 30-minute AEO rating. 

(c) Section 33.87, Endurance Test. In 

addition to the requirements of 

§§ 33.87(a) and 33.87(d), the overall test 

run must include a minimum of 25 

hours of operation at 30-minute AEO 

power and limits, divided into periods 

of 30-minutes AEO power with alternate 

periods at maximum continuous power 

or less. 

(1) Modification of the § 33.87 test 

requirements to include the 25 hours of 

operation at 30-minute AEO power 

rating must be proposed by the 

Applicant and accepted by the FAA. 

(2) Each § 33.87(d) continuous oneengine-inoperative (OEI) rating test 

period of 30-minutes or longer, run at 

power and limits equal to or higher than 

the 30-minutes AEO rating, may be 

credited toward this requirement. Note 

that the test time required for the takeoff 

or other OEI ratings may not be counted 

toward the 25 hours of operation 

required at the 30-minute AEO rating.
