89-17-05 BELL HELICOPTER TEXTRON, INC.: Amendment 39-6276.
Applicability: Model 222, 222B, and 222U helicopters, certificated in any category, with horizontal stabilizer assembly, Part Number (P/N) 222-035-250-101, -103, or -105, installed. (Docket No. 89-ASW-16)
Compliance: Required within the next 50 hours' time in service for horizontal stabilizer assemblies with more than 2,100 hours' time in service; compliance for horizontal stabilizers with less than 2,100 hours' time in service is required prior to the accumulation of 2,150 hours' time in service; and both thereafter at intervals not to exceed 300 hours' time in service.
To prevent failure of the horizontal stabilizer assembly, which could result in loss of the helicopter, accomplish the following:
(a) Perform the Part "A" of the "Accomplishment Instructions" of BHTI Alert Service Bulletin (ASB) No. 222-89-53, dated March 20, 1989, for the Model 222 and 222B; or ASB No. 222U-89-27, dated March 20,1989, for the Model 222U.
(b) If a crack is detected, remove and replace with a serviceable horizontal stabilizer assembly prior to further flight.
(c) The requirements of this AD do not apply if horizontal stabilizer assembly P/N 222-035-250-107 is installed for the Model 222 or P/N 222-035-250-109 is installed for the Models 222B and 222U.
(d) An alternate method of compliance which provides an equivalent level of safety, may be approved by the Manager, Rotorcraft Certification Office, Southwest Region, Federal Aviation Administration, Fort Worth, Texas 76193-0170.
The inspection procedures shall be done in accordance with Part "A" of the "Accomplishment Instructions" of BHTI Alert Service Bulletin (ASB) No. 222-89-53, dated March 20, 1989, for the Model 222 and 222B; or ASB No. 222U-89-27, dated March 20, 1989, for the Model 222U.
This incorporation by reference of ASB No 222-89-53 and ASB No. 222U-89-27, both dated March 20, 1989, was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51.
