The airworthiness directive
64-16-06 PIPER: Amdt. 767 Part 507 Federal Register July 21, 1964. Applies to Model PA-30 Aircraft, Serial Numbers 30-41, 30-82, 30-83, 30-104 and 30-123.
Compliance required within 25 hours' time in service after the effective date of this AD unless already accomplished.
Because of the possible presence of welds with inadequate penetration in the nose gear retraction tube, replace the present tube with a redesigned nose gear retraction tube, Piper P/N 21109-05.
NOTE: The new tube can be identified by the two bead weld slots on each end of the tube.
(Piper Service Letter No. 409, dated October 9, 1963, provides replacement method instructions.)
This directive effective August 20, 1964.
