## The airworthiness directive

75-17-06 SIAI-MARCHETTI: Amendment 39-2307. Applies to Models F.260 and F.260B, all serial numbers, certificated in all categories.

Compliance is required within the next 10 hours time in service after the effective date of this AD, unless already accomplished.

To provide instructions for the correct operation of the emergency landing gear control, replace the "Emergency Landing Gear Extension" procedure set forth on page 9 of the airplane Flight Manual with a copy of the procedure set forth in SIAI Service Bulletin S.B.No.260B5, dated December 23, 1970, or an FAA-approved equivalent. Retain a copy of the procedure of Service Bulletin S.B.No. 260B5, or an FAA-approved equivalent, in the airplane Flight Manual until the procedure has been incorporated by the approved revision dated August 9, 1973 into the airplane Flight Manual.

This amendment becomes effective August 15, 1975.

## NTSB investigations that cite this AD (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
