The airworthiness directive
73-17-01 CESSNA: Amdt. 39-1701. Applies to all series of Cessna Models 170, 172, 175, 180 and 182 airplanes equipped with the 18 gallon auxiliary fuel tank manufactured by the Javelin Aircraft Company, Wichita, Kansas.
Compliance: Required within 100 hours time in service after the effective date of this AD, unless already accomplished.
To advise the pilot concerning proper fuel transfer pump operation, install Javelin Placard 782-14 or an equivalent FAA-approved placard, adjacent to the fuel transfer pump switch which reads as follows: "AUXILIARY FUEL TRANSFER PUMP. PULL ON. PUSH OFF. PLACE PUMP OFF BEFORE CHANGING FROM LEFT TANK."
NOTE: Failure to turn off fuel boost pump allows air to enter engine fuel system and may cause engine power failure when fuel selector valve is changed from left tank position.
Cessna Service Letter No. SE69-24 dated November 21, 1969, or subsequent FAA-approved revisions cover this subject matter.
This amendment becomes effective August 16, 1973.
