Plain English Summary

3/10 complexity

Requires owners/operators of Pitts S-1 and S-2 aeroplanes (except S-2B serial 5337 and later) to inspect the rear lower fuselage wing fittings within 50 flight hours and then every 50 hours until repaired per the Aviat Service Bulletin; the directive references FAA AD 96-12-03 R2. A cracked fitting can lead to in-flight wing separation, so operators pay for inspections, repairs and scheduling of recurring maintenance to meet the directive.

Applicability: All models, except model S-2B serial number 5337 and on.

Requirement: Action in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Aviat Aircraft Service Bulletin No.25 dated April 3 1996, initial issue or as revised 12 November 1996 or 11 November 1997.

Note: FAA AD 96-12-03 R2 refers.

This Amendment becomes effective on 25 February 1999.

Background: Cracking of the rear lower fuselage fittings has been discovered in models S-2. The same fitting is also used in Models S-1. A cracked fitting may cause an in flight wing separation.

Amendment 1 excluded certain model S-2B aircraft, which have an improved rear lower fuselage wing fitting incorporated during manufacture, and updated the referenced requirement document and FAA airworthiness directive.

This amendment revises the applicability to S-2B aircraft and updates the referenced requirement document and FAA airworthiness directive. The improved rear lower fuselage wing fitting was installed commencing with aircraft serial number 5337, not 5349 as stated in the earlier directive.

Amendment 1 of this Airworthiness Directive became effective on 6 November 1997. The original issue of this Airworthiness Directive became effective on 17 July 1996.
