Airworthiness Directives; Boeing

Model 777–200 and –300 Series

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment supersedes

an existing airworthiness directive (AD),

applicable to all Boeing Model 777–200

and –300 series airplanes, that currently

requires revising the Limitations Section

of the Airplane Flight Manual (AFM) to

prohibit the dispatch of certain

airplanes under certain conditions. That

amendment also requires repetitive

inspections to ensure correct operation

of the backup generators; and, for

certain airplanes, a one-time inspection

to detect damage of the engine external

gearbox; and corrective actions, if

necessary. This amendment continues

the AFM and inspection requirements

and expands certain corrective action

requirements. This amendment is

prompted by reports of inflight

shutdowns due to sheared backup

generator shafts. The actions specified

in this AD are intended to prohibit the

dispatch of an airplane with an enginemounted backup generator having a

sheared shaft; and to detect and correct

damage to the engine, which could

result in inflight shutdowns.

DATES: Effective July 13, 2000.

The incorporation by reference of

certain publications, as listed in the

regulations, was approved previously by

the Director of the Federal Register as of

December 23, 1999 (64 FR 68618,

December 8, 1999).

Comments for inclusion in the Rules

Docket must be received on or before

August 28, 2000.

SUPPLEMENTARY INFORMATION: On

November 30, 1999, the FAA issued AD

99–25–13, amendment 39–11456 (64 FR

68618, December 8, 1999), applicable to

all Boeing Model 777–200 and –300

series airplanes, to require revising the

Limitations Section of the Airplane

Flight Manual to prohibit the dispatch

of certain airplanes under certain

conditions. That AD also requires

repetitive inspections to ensure correct

operation of the backup generators; and,

for certain airplanes, a one-time

inspection to detect damage of the

engine external gearbox; and corrective

actions, if necessary.

A correction of the final rule was

published in the Federal Register on

December 22, 1999 (64 FR 71635,

December 23, 1999). That AD (AD 99–

25–13 C1, amendment 39–11456)

corrects incorrect paragraph references

in AD 99–25–13. That action was

prompted by reports of inflight

shutdowns due to sheared backup

generator shafts. The actions required by

the correction AD are intended to

prohibit the dispatch of an airplane with

an engine-mounted backup generator

having a sheared shaft; and to detect

and correct damage to the engine, which

could result in inflight shutdowns.

Actions Since Issuance of Previous Rule

Since the issuance of AD 99–25–13

C1, the FAA has received questions

from an operator regarding the following

corrective action procedures:

• Boeing Service Letter 777–SL–24–

023–B, dated August 16, 1999, specifies

accomplishment of the applicable

actions specified in both Steps 2.a.(1)

and 2.a.(2) of that service letter.

However, paragraph (d)(1)(ii) in that AD

requires the accomplishment of either

Steps 2.a.(1) or 2.a.(2), as applicable.

• Boeing Service Letter 777–SL–24–

024, dated August 16, 1999, specifies

accomplishment of the applicable

actions specified in both Steps 1.a.(1)

and 1.a.(2) of that service letter.

However, paragraph (d)(2) in that AD

requires the accomplishment of either

Steps 1.a.(1) or 1.a.(2), as applicable.

In response to the operator’s

questions, the FAA has determined that

it is necessary to require the

accomplishment of both of the

applicable corrective actions specified

in paragraph (d)(1)(ii) in that AD [cited

as paragraph (f)(1)(ii) in this AD] for

airplanes equipped with certain RollsRoyce engines, and both of the

applicable corrective actions specified

in paragraph (d)(2) in that AD [cited as

paragraph (f)(2) of this AD] for airplanes

equipped with certain General Electric

engines.

In addition, paragraphs (d)(1)(ii) and

(d)(2) in that AD should have specified

that the corrective actions required by

those paragraphs are specified in certain

Federal Register / Vol. 65, No. 125 / Wednesday, June 28, 2000 / Rules and Regulations 39789

steps ‘‘of the service letter.’’ That service

letter clarification has been added to

paragraphs (f)(1)(ii) and (f)(2) of this AD,

accordingly.

Paragraphs (d)(3), (d)(3)(i), and

(d)(3)(ii) in that AD are cited as

paragraphs (d), (d)(1), and (d)(2) of this

AD for airplanes equipped with certain

Pratt & Whitney engines. Other

paragraphs of this AD also have been

reformatted.

Explanation of Requirements of Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of this same

type design, this AD supersedes AD 99–

25–13 C1 to continue to require revising

the Limitations Section of the Airplane

Flight Manual to prohibit the dispatch

of certain airplanes under certain

conditions; repetitive inspections to

ensure correct operation of the backup

generators; and, for certain airplanes, a

one-time inspection to detect damage of

the engine external gearbox; and

corrective actions, if necessary. This

amendment also expands the

requirements for certain corrective

actions.

Determination of Rule’s Effective Date

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in less than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an opportunity

for public comment, comments are

invited on this rule. Interested persons

are invited to comment on this rule by

submitting such written data, views, or

arguments as they may desire.

Communications shall identify the

Rules Docket number and be submitted

in triplicate to the address specified

under the caption ADDRESSES. All

communications received on or before

the closing date for comments will be

considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.

Submit comments using the following

format:

• Organize comments issue-by-issue.

For example, discuss a request to

change the compliance time and a

request to change the service bulletin

reference as two separate issues.

• For each issue, state what specific

change to the AD is being requested.

• Include justification (e.g., reasons or

data) for each request.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before

and after the closing date for comments,

in the Rules Docket for examination by

interested persons. A report that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.

Commenters wishing the FAA to

acknowledge receipt of their comments

submitted in response to this rule must

submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 2000–NM–108–AD.’’

The postcard will be date stamped and

returned to the commenter.

Regulatory Impact

The regulations adopted herein will

not have a substantial direct effect 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, it is

determined that this final rule does not

have federalism implications under

Executive Order 13132.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and that it is not a ‘‘significant

regulatory action’’ under Executive

Order 12866. It has been determined

further that this action involves an

emergency regulation under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979). If it is

determined that this emergency

regulation otherwise would be

significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket.

A copy of it, if filed, may be obtained

from the Rules Docket at the location

provided under the caption ADDRESSES.
