Airworthiness Directives; McDonnell

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to all McDonnell Douglas

Model DC–10 and MD–11 series

airplanes, and KC–10A (military)

airplanes, that requires installation of

thrust reverser interlocks on certain

airplanes, inspections of the thrust

reverser systems to detect discrepancies

on certain other airplanes, and

corrective actions, if necessary. This

amendment is prompted by a

determination that the current thrust

reverser systems do not adequately

preclude unwanted deployment of a

thrust reverser. The actions specified by

this AD are intended to prevent

unwanted deployment of a thrust

reverser, which could result in reduced

controllability of the airplane.

DATES: Effective April 25, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of April 25,

2001.

referenced in 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 airworthiness directive (AD)

that is applicable to all McDonnell

Douglas Model DC–10 and MD–11

series airplanes, and KC–10A (military)

airplanes, was published in the Federal

Register on November 30, 1999 (64 FR

66816). That action proposed to require

installation of thrust reverser interlocks

on certain airplanes, inspections of the

thrust reverser systems to detect

discrepancies on certain other airplanes,

and corrective actions, if necessary.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. Due

consideration has been given to the

comments received.

All commenters agree with the intent

of the proposed AD; however, some of

them request that certain aspects of the

proposed AD be revised.

Requests to Revise Certain Compliance

Times

Two commenters request that the

proposed compliance time (i.e., within

1,500 flight hours or 6 months after the

effective date of this AD, whichever

occurs first) specified in paragraphs (a),

(b), and (c) of the proposed AD be

revised. One commenter suggests a

compliance time of ‘‘6,000 flight hours

or 18 months, whichever occurs first.’’

This commenter states that such an

extension will allow the proposed

actions to be done at a ‘‘Light Check’’

where special equipment and trained

maintenance personnel will be

available, if necessary, instead of during

line maintenance. The second

commenter suggests ‘‘3,000 flight hours

or 12 months after the AD effective

date.’’ This commenter states that such

an extension will allow affected

operators to do the proposed actions

during a regularly scheduled

maintenance interval, thereby

preventing service disruptions.

The FAA does not agree with the first

commenter’s request to extend the

compliance time to ‘‘6,000 flight hours

or 18 months, whichever occurs first.’’

However, we agree with the second

commenter’s request to extend the

compliance time to ‘‘within 3,000 flight

hours or 12 months after the effective

date of this AD, whichever occurs first.’’

Extending the compliance time by an

additional 1,500 flight hours or 6

months will not adversely affect safety

and will allow the actions required by

paragraphs (a), (b), and (c) of this AD to

be performed at a base during regularly

scheduled maintenance where special

equipment and trained maintenance

personnel will be available if necessary.

Extending the compliance time beyond

3,000 flight hours or 12 months after the

effective date of this AD may affect

safety. In addition, no information has

been provided to justify the extension

beyond this time. Therefore, we have

revised paragraphs (a), (b), and (c) of the

final rule accordingly.

One commenter requests that the

compliance time specified in paragraphs

(d)(1) and (d)(2) of the proposed AD be

revised to include a grace period of ‘‘or

at the next scheduled [Certification
