Airworthiness Directive · Amendment 39-15024 · Stabilizers
LATINOAMERICANA DE AVIACIÓN (LAVIA) S.A. (Type Certificate Data Sheets No. 2A8 and No. 2A10 Previously Held by The New Piper Aircraft, Inc.) Models PA-25, PA-25-235, and PA-25-260 Airplanes
This AD applies to Models PA-25, PA-25-235, and PA-25-260, all serial numbers up to LA-260-06008, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI references Latinoamericana de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, which describes the unsafe condition as:
Unless already done, do the following actions:
(1) Upon accumulating 1,500 hours time-in-service (TIS) or within the next 50 hours TIS after May 18, 2007 (the effective date of this AD), whichever occurs later, do the operations as specified in the paragraph “ACTIONS,” subparagraph “INITIAL” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006. Repetitively inspect thereafter every 100 hours TIS or 12 months, whichever occurs first, until the modification specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, is done.
(2) If any evidence of cracks, signs of corrosion, or any other discrepancy is detected during any inspection required in paragraph (f)(1) of this AD, before further flight, disassemble both horizontal stabilizers and conduct a detailed inspection on the surface of both supports and take corrective action. Use paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006.
(3) After incorporating the modification specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, no further action is required.
(4) Upon accumulating 1,000 hours TIS after May 18, 2007 (the effective date of this AD), modify both horizontal stabilizers as specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, unless already done. Incorporating this modification terminates the repetitive inspection requirement in paragraph (f)(1) of this AD.
(5) As a terminating action to the inspection requirements of this AD, the modification to both horizontal stabilizers specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, may be incorporated at any time after the effective date of this AD and before the time required in paragraph (f)(4) of this AD.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
