14 CFR Part 39

[Docket No. 92-CE-23-AD; Amendment 39-9319; AD 95-15-13]


Airworthiness Directives; Jetstream Aircraft Limited (Formerly 
British Aerospace, Regional Aircraft Limited) Jetstream Models 3101 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) Jetstream Models 3101 and 
3201 airplanes.This action requires inspecting the main passenger/crew 
door locking mechanism to ensure that a taper pin is installed, 
installing a taper pin if not already installed, and modifying the 
passenger door warning system. The actions specified by this AD are 
intended to prevent the inability to open the passenger/crew door or 
failure of the passenger door warning system, which could result in 
passenger injury if emergency evacuation is needed.

DATES: Effective September 7, 1995.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 7,1995.

ADDRESSES: Service information that applies to this AD may be obtained

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an AD that would apply 
to certain JAL Models 3101 and 3201 airplanes was published in the 
Federal Register on February 22, 1995 (60 FR 9794). The action proposed 
to require inspecting the main passenger/crew door locking mechanism to 
ensure that a taper pin is installed, installing a taper pin if not 
already installed, and modifying the passenger door warning system. 
Accomplishment of the proposed inspection and possible installation 
would be in accordance with Jetstream Service Bulletin (SB) 52-A-
JA911140, which incorporates the following pages:

    Accomplishment of the proposed door warning system modification 
would be in accordance with Jetstream SB 52-JM 7793, which incorporates 
the following pages:

------------------------------------------------------------------------

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposed rule or the FAA's determination of the cost to the public.
    After careful review of all available information related to the 
subject presented above, the FAA has determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. The FAA has determined that these minor 
corrections will not change the meaning of the AD and will not add any 
additional burden upon the public than was already proposed.
    The FAA estimates that 200 airplanes in the U.S.registry will be 
affected by this AD, that it will take approximately 10 work hours (2 
workhours for the taper pin installation and 8 workhours for the 
passenger door warning system modification) per airplane to accomplish 
the required action, and that the average labor rate is approximately 
$60 an hour. Parts to accomplish the modifications will be provided by 
JAL at no cost to the owner/operator. Based on these figures, the total 
cost impact of this AD on U.S. operators is estimated to be $120,000. 
This figure is based on the assumption that no affected owner/operator 
has accomplished either of the modifications; that all airplanes will 
need a taper pin installed on the passenger/crew door locking 
mechanism; and that no airplane owner/operator has accomplished the 
passenger door warning system modification. The FAA anticipates that a 
majority of the affected airplanes already have taper pins installed 
and passenger door warning system modifications incorporated, thereby 
reducing the cost impact upon the public.
    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 copy of the final evaluation prepared for this 
action is contained in the Rules Docket. A copy of it may be obtained 
by contacting 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 U.S.C. App. 1354(a), 1421 and 1423; 49 U.S.C. 
106(g); and 14 CFR 11.89.


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding a new AD to read as follows:

95-15-13  Jetstream Aircraft Limited: Amendment 39-9319; Docket No. 
92-CE-23-AD.

    Applicability: Jetstream Models 3101 and 3201 airplanes (all 
serial numbers), certificated in any category.

    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 (d) 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 within the next 500 hours time-in-service 
after the effective date of this AD, unless already accomplished.
    To prevent the inability to open the passenger/crew door or 
failure of the passenger door warning system, which could result in 
passenger injury if emergency evacuation is needed, accomplish the 
following:
    (a) For all affected airplanes that have a main passenger/crew 
door installed with one of the following serial numbers, accomplish 
paragraphs (a)(1) and (a)(2) of this AD, as applicable:

WIPL-SD-0001 through WIPL-SD-0005,
WIPL-SD-0008 through WIPL-SD-0031,
WIPL-SD-0034 through WIPL-SD-0046,
WIPL-SD-0049, WIPL-SD-0051 through WIPL-SD-0065,
WIPL-SD-0067, WIPL-SD-0070, WIPL-SD-0071,
SDJ10883, SDJ10884A, SDJ10884B, and SDJ10886 through SDJ10891

    (1) To ensure that a part number SP28E4 taper pin is installed, 
visually inspect the passenger/crew door locking mechanism in the 
area between the locking dog and indicator button assembly in 
accordance with Part 2 of the ACCOMPLISHMENT INSTRUCTIONS section of 
Jetstream Service Bulletin (SB) 52-A-JA 911140, which incorporates 
the following pages:

sections 21.197 and 21.199 

[[Page 38954]]
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.

compliance times that provides an equivalent level of safety may be 
approved by the Manager, Brussels Aircraft Certification Office 
(ACO), FAA, Europe, Africa, and Middle East Office, c/o American 
Embassy, B-1000 Brussels, Belgium. The request should be forwarded 
through an appropriate FAA Maintenance Inspector, who may add 
comments and then send it to the Manager, Brussels ACO.

    Note 3: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Brussels ACO.
