AD: Aircraft-Manufactured Model S- 64F Helicopters

AD NUMBER: 2012-26-06

PRODUCT: Sikorsky Aircraft Corporation-manufactured Model S-64F helicopters, now under the Erickson Air-Crane Incorporated (Erickson) Model S-64F type certificate.
SUBJECT: Airworthiness Directive 2012-26-06
ACTION: Final Rule

SUMMARY:  This AD supersedes an existing AD which requires inspections, rework, and replacement, if necessary, of the main gearbox (MGB) second stage lower planetary plate (plate).

Since that AD was issued, the manufacturer has conducted a configuration review and analysis, and a review of the service history of certain components. The actions of this AD are intended to establish life limits for certain components, remove various parts from service, and require consistency in the part numbers of certain four bladed tail rotor (T/R) assemblies to prevent fatigue cracking, failure from static overload, and subsequent loss of control of the helicopter.

DATES: This AD is effective April 16, 2013.

FMI: AD
