(h) The following provisions also apply to
(1) Alternative Methods of Compliance
(AMOCs): The Manager, New York Aircraft
Certification Office (ACO), ANE-170, FAA,
has the authority to approve AMOCs for this
AD, if requested using the procedures found

as appropriate, or lacking a principal
inspector, your local Flight Standards District
Office. The AMOC approval letter must
specifically reference this AD.
(2) Airworthy Product: For any
requirement in this AD to obtain corrective
actions from a manufacturer or other source,
use these actions if they are FAA-approved.
Corrective actions are considered FAA-

Airworthiness Directives; Rolls-Royce
plc RB211-Trent 768, 772, and 772B
AGENCY: Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
SUMMARY: We propose to rescind an
airworthiness directive (AD) for the
products listed above. The existing AD,
AD 98-09-27, resulted from aircraft
certification testing which revealed that
stresses on the thrust reverser hinge
were higher than had been anticipated
during engine certification, and the
United Kingdom Civil Aviation
Authority, issuing AD 008-03-97.
Since we issued AD 98-09-27, we
discovered that its requirements were
duplicated in airplane-level AD 2001-
09-14, issued by the FAA Transport
Airplane Directorate. This proposal to
rescind the engine-level AD allows the
public the opportunity to comment on
the FAA's determination of the
duplication of requirements in another
AD, before we rescind the engine-level
DATES: We must receive comments on
this proposed AD by December 30,
