This AD does not apply to those airplanes on which Cessna P/Ns 1280511-3/4 and 1298100-1/2 actuator assemblies are installed.
Compliance: Required as indicated, unless already accomplished in accordance with this AD, previous maintenance or AD 71-24-07.
To decrease the possibility of main gear extension failure, accomplish the following:
On or before April 1, 1977, or within 100 hours' time in service after February 26, 1976, whichever occurs later, install Cessna Kits 1209005-1 R/L in accordance with Cessna Service Letter SE75-21 dated October 3, 1975, or later approved revisions, or an equivalent method approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.
NOTE 1) The landing gear actuator assemblies having Cessna P/Ns and manufactured by Electrol can be identified by using an inspection mirror through the inspection plate located forward of the strut doors to read the actuator nameplate.
NOTE 2) A significant savings of manhours will result if compliance with this AD and the modifications and/or inspections required by AD 76-14-07 (Amendment 39-2670 - landing gear saddle fittings) are accomplished at the same time.
NOTE 3) It is imperative that Cessna P/N 1209005-1 R/L Kits be ordered from the manufacturer immediately to assure that a sufficient supply of kits will be available to allow modification of all affected aircraft on or before April 1, 1977.
