Background

On June 7, 1994, Jetstream Aircraft

Limited applied for approval of a design

change (without a new airplane model

designation) to Type Certificate No.

A41NM for the installation of a CPR

system on the Jetstream Model 4101

airplane. The Jetstream Model 4101 is a

30 passenger, 23,000 pounds maximum

take-off weight, transport category

airplane with two Allied Signal

TPE331–14GR/HR series turbopropeller

engines. The CPR system makes a CPR

power rating available for the final takeoff climb and en route phases of flight

after failure of one engine.

The CPR power rating for this engine

installation is equivalent to the

maximum continuous power rating

established for the engine under Part 33

of the Federal Aviation Regulations

(FAR). Following engine failure, the

CPR system automatically increases the

engine maximum exhaust gas

temperature (EGT) limit, which permits

the operating engine’s maximum

continuous power rating to be obtained

at higher ambient air temperatures.

Increased engine hour and cycle

maintenance factors apply for CPR

power rating operation. Since the CPR

power rating will only be available

during engine-out conditions, the

maximum power normally available

with all engines operating will be less

than the part 33 certified maximum

continuous power rating at certain

higher ambient temperature ranges.

The CPR system is novel when

compared to those systems envisaged

when the applicable regulations in part

25 were promulgated. Therefore, the

airworthiness regulations in part 25 do

not contain adequate or appropriate

safety standards for airplanes with CPR

systems installed. Special conditions are

therefore prescribed to supplement the

certification basis of record for the

Jetstream Model 4101 airplane with a

CPR system installed.

Type Certification Basis

Under the provisions of § 21.101,

Jetstream Aircraft Limited must show

that the Jetstream Model 4101, as

changed, continues to meet the

applicable provisions of the regulations

incorporated by reference in Type

Certificate No. A41NM or the applicable

regulations in effect on the date of

application for the change. The

regulations incorporated by reference in

the type certificate are commonly

referred to as the ‘‘original type

certification basis.’’ The regulations

incorporated by reference in Type

Certificate No. A41NM are part 25 of the

FAR dated February 1, 1965, as

amended by Amendments 25–1 through

25–66. The regulations incorporated by

reference also include certain special

conditions, exemptions, and later

amended sections of Part 25 that are not

relevant to these proposed special

conditions.

If the regulations incorporated by

reference do not provide adequate

standards with respect to the change,

the applicant must comply with certain

regulations in effect on the date of

application for the change. The FAA has

determined that the areas of the

Jetstream Model 4101 that are affected

by the installation of the CPR system

must also be shown to comply with all

sections of part 25 as amended by

Amendments 25–1 through 25–81 in

effect on the date of application.

If the Administrator finds that the

applicable airworthiness regulations

(i.e., part 25 as amended) do not contain

adequate or appropriate safety standards

for the Jetstream Model 4101 because of

a novel or unusual design feature,

special conditions are prescribed under

the provisions of § 21.16. When

appropriate, special conditions are

issued in accordance with § 11.49 of the

FAR after public notice, as required by

§§ 11.28 and 11.29(b), and become part

of the type certification basis in

accordance with § 21.101(b)(2). 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 or should any

other model already included on the

same type certificate be modified to

incorporate the same novel or unusual

design feature, the special conditions

would also apply to the other model

under the provisions of § 21.101(a)(1).

In addition to the applicable

airworthiness regulations and special

conditions, the Jetstream Model 4101

must comply with the fuel vent and

exhaust emission requirements of part

34 and the noise certification

requirements of part 36.

Novel or Unusual Design Features

The Jetstream Model 4101 will

incorporate a CPR system that provides

an engine power rating (as defined on

the airplane) that is equivalent to the

engine’s part 33 certified maximum

continuous power rating. Since the CPR

power rating will only be available

during engine-out conditions, the

maximum power available with all

engines operating will normally be less

than the part 33 certified maximum

continuous power rating at certain

higher ambient temperatures. The CPR

system is integrated into the existing

approved Automatic Power Reserve

(APR) system. On the Jetstream 4100

airplane, the APR system is equivalent

to an Automatic Takeoff Thrust Control

System (ATTCS) as defined in

Appendix I of Part 25. The currently

approved APR system automatically

makes additional thermodynamic power

and torque available on the operating

engine after engine failure during

takeoff and for approach climb (goaround). For certain ambient

temperature ranges, the proposed CPR

system automatically increases the

engine’s EGT limit and torque available

on the operating engine for final take-off

climb and en route flight phases after

failure of one engine. The CPR-related

increased EGT limit, which is above the

two-engines-operating EGT maximum

continuous power and take-off limits,

enables the operating engine to achieve

the flat-rated maximum continuous

power (torque) level at higher outside

air temperature (OAT). Engine operation

in the APR and CPR modes requires

application of engine hour and cycle

maintenance factors as specified in

engine Type C Certificate Data Sheet

E18NE.

As discussed above, these special

conditions are applicable to the

Jetstream Model 4101. Should Jetstream

Aircraft Limited 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 under the provisions

of § 21.101(a)(1).

Conclusion

This action affects only certain novel

or unusual design features on one model

of airplane. It is not a rule of general

applicability, and it affects only the

applicant who applied to the FAA for

approval of these features on the

airplane.

Federal Register / Vol. 62, No. 50 / Friday, March 14, 1997 / Proposed Rules 12121

Installation of a Continuous Power

Reserve (CPR) System

(a) General. With the CPR system

functioning normally as designed, all

applicable requirements of part 25 must

be met without requiring any unusual

action (other than arming the system

prior to dispatch) by the crew to set

power or thrust.

(b) Performance and Reliability

Requirements.

(1) A CPR failure or combination of

failures.

(i) That prevents the automatic

insertion of CPR thrust or power must

be shown to be an improbable event;

(ii) That prevents the automatic

insertion of APR thrust or power during

the critical time interval defined in

Appendix I of Part 25 must be shown to

be an improbable event; and

(iii) Shall not result in the significant

loss or reduction in thrust or power, or

must be shown to be an extremely

improbable event.

(2) All applicable performance

requirements of part 25 must be met

with an engine failure occurring at the

most critical time with the CPR system

functioning.

(c) Thrust Setting. The maximum

continuous thrust or power setting

specified for use with all engines

operating may not be less than any of

the following:

(1) Ninety (90) percent of the thrust or

power set by the CPR system for which

AFM performance credit is approved;

(2) That required to permit normal

operation of all safety-related systems

and equipment dependent upon engine

thrust or power lever position; or

(3) That shown to be free of hazardous

engine response characteristics when

thrust or power is advanced from the

initial all-engines-operating thrust or

power setting to the maximum approved

maximum continuous/CPR mode thrust

or power setting.

(d) Powerplant Controls.

(1) In addition to the requirements of

§ 25.1141, no single failure or

malfunction, or probable combination

thereof, of the CPR, including associated

systems, may cause the failure of any

powerplant function necessary for

safety.

(2) The CPR system must be designed

to:

(i) In the event of a CPR system

failure, permit manual decrease or

increase in thrust or power up to the

highest maximum continuous thrust or

power approved for the airplane under

existing conditions through the use of

the power lever. For airplanes equipped

with limiters that automatically prevent

engine operating limits from being

exceeded under existing ambient

conditions, other means may be used to

increase the thrust or power in the event

of a CFR failure provided the means is

located on or forward of the power

levers; is easily identified and operated

under all operating conditions by a

single action of either pilot with the

hand that is normally used to actuate

the power levels; and meets the

requirements of § 25.777 (a),(b), and (c).

(ii) Provide a means for the flightcrew

to deactivate the automatic CPR

function. This means must be designed

to prevent inadvertent deactivation.

(iii) Provide a means for the

flightcrew to verify that the CFR system

is in a condition to operate.

(e) Powerplant Instruments. In

addition to the requirements of

§ 25.1305, a means must be provided to

indicate when the CPR is in the armed

or ready condition.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to all

Boeing Model 737–100, –200, –300,

–400, and –500 series airplanes. This

proposal would require installation of a

newly designed rudder-limiting device

and yaw damper system. This proposal

is prompted by a report indicating that

a full rudder input, either commanded

or uncommanded, could result in a

rapid roll upset; and by reports of

malfunctions of the yaw damper system.

The actions specified by the proposed

AD are intended to prevent excessive

rudder authority and consequent

reduced controllability of the airplane;

and malfunctions of the yaw damper

system, which could result in sudden

uncommanded yawing of the airplane

and consequent injury to passengers and

crewmembers.
