58-01-06 PIPER: Applies to Model PA-23 Aircraft, Serial Numbers 23-1 to 23-1219 Inclusive.
Compliance required as indicated.
Due to the installation of the front stabilizer-to-fuselage attachment fitting P/N 17093-00, on additional aircraft to those covered by AD 57-13-09 and since special inspections are not required when the redesigned fitting P/N 17093-03 is installed, this supersedes the portions of AD 57-13-09 concerning this fitting and revision issued on Card No. 57-22.
Inspect visually for cracks, the front stabilizer fitting, P/N 17093-00 every 100 hours until replaced with the redesigned fitting P/N 17093-03. Fittings found cracked must be replaced.
(Piper Service Bulletin No. 160 dated October 7, 1957, covers the same subject.)
