Airworthiness Directives; Cessna

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Cessna Model 441,

500, 550, and 560 series airplanes, that

requires replacement of outflow/safety

valves with serviceable valves. This

amendment is prompted by a report of

cracking and subsequent failure of

outflow safety valves in the

pressurization system. The actions

specified by this AD are intended to

prevent such cracking and subsequent

failure of the outflow/safety valves,

which could result in rapid

decompression of the airplane.

DATES: Effective January 22, 1996.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of January 22,

1996.

ADDRESSES: The service information

referenced in this AD may be obtained

from Allied Signal, Inc., Controls and

Accessories, 1110 North Oracle Road,

information may be examined at the

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to Cessna Model 441,

500, 550, and 560 series airplanes was

published in the Federal Register on

August 18, 1995 (60 FR 43089). That

action proposed to require replacement

of certain discrepant outflow/safety

valves with serviceable valves.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

The FAA has determined that air safety

and the public interest require the

adoption of the rule as proposed.

There are approximately 150 Model

441, 500, 550, and 560 series airplanes

of the affected design in the worldwide

fleet. The FAA estimates that 120

airplanes of U.S. registry will be affected

by this AD, that it will take

approximately 12 work hours per

airplane to accomplish the required

actions, and that the average labor rate

is $60 per work hour. Based on these

figures, the cost impact of the AD on

U.S. operators is estimated to be

$86,400, or $720 per airplane. However,

the manufacturer has advised that it will

provide replacement parts at no cost to

the operator and will reimburse

operators for the labor costs of the

required removal and replacement.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish

those actions in the future if this AD

were not adopted.

The regulations adopted herein will

not have substantial direct effects 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. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (1) Is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979); and (3)

will not have a significant economic

impact, positive or negative, on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends part 39 of the

Federal Aviation Regulations (14 CFR

part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 USC 106(g), 40101, 40113,

44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

95–25–10 Cessna Aircraft Company:

Amendment 39–9456. Docket 95–NM–

56–AD.

Applicability: Model 441, 500, 550, and

Federal Register / Vol. 60, No. 246 / Friday, December 22, 1995 / Rules and Regulations 66485

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must use the authority

provided in paragraph (c) of this AD to

request approval from the FAA. This

approval may address either no action, if the

current configuration eliminates the unsafe

condition; or different actions necessary to

address the unsafe condition described in

this AD. Such a request should include an

assessment of the effect of the changed

configuration on the unsafe condition

addressed by this AD. In no case does the

presence of any modification, alteration, or

repair remove any airplane from the

applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

To prevent cracking and subsequent failure

of the outflow/safety valves, which could

result in rapid decompression of the airplane,

accomplish the following:

(a) Within 18 months after the effective

date of this AD, replace the outflow/safety

valve in accordance with Allied Signal

Aerospace Service Bulletin 103576–21–4054

(for Model 441 series airplanes), 103576–21–

4056 (for Model 500 and 550 series

airplanes), or 103648–21–4055 (for Model

560 series airplanes), all dated January 30,

1995, as applicable.

(b) As of the effective date of this AD, no

person shall install an outflow/safety valve,

having a part number and serial number

identified in Allied Signal Aerospace Service

Bulletin 103576–21–4054 (for Model 441

series airplanes), 103576–21–4056 (for Model

500 and 550 series airplanes), or 103648–21–

4055 (for Model 560 series airplanes), all

dated January 30, 1995, on any airplane

unless that valve is considered to be

serviceable in accordance with the applicable

service bulletin.

(c) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager, Los

Angeles Aircraft Certification Office (ACO),

FAA, Transport Airplane Directorate.

Operators shall submit their requests through

an appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, Los Angeles ACO.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Los Angeles ACO.

(d) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

(e) The replacement shall be done in

accordance with Allied Signal Aerospace

Service Bulletin 103576–21–4054, dated

January 30, 1995; Allied Signal Aerospace

Service Bulletin 103576–21–4056, dated

and 3201 Airplanes.

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that

applies to Jetstream Aircraft Limited

(JAL) HP137 Mk1, Jetstream Series 200,

and Jetstream Models 3101 and 3201

Airplanes. This action requires

inspecting (one-time) the threaded

portion of the aileron mounting spigots

for cracks, replacing any cracked

spigots, and replacing the securing nut

assemblies with newly designed special

nut assemblies and new split pins.

Reports of cracked aileron mounting

spigots caused by stress corrosion

prompted this action. The actions

specified by this AD are intended to

prevent damage to the aileron control

systems, which if not detected and

corrected, could cause loss of lateral

control and eventual loss of control of

the airplane.

DATES: Effective January 17, 1996.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director
