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. ## Affected data sheets (5) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS 3A13](https://openairdocs.org/tcds/3A13): Textron Aviation Inc.; names 19 of 23 models: 182D, 182A, 182J, 182P, 182B, 182L, 182G, 182Q… - [TCDS 3A12](https://openairdocs.org/tcds/3A12): Textron Aviation Inc.; names 18 of 18 models: 172F (USAF T-41A), 172M, 172Q, 172R, 172K, 172G, 172A, 172L… - [TCDS 5A6](https://openairdocs.org/tcds/5A6): Textron Aviation Inc.; names 11 of 11 models: 180E, 180J, 180F, 180H, 180A, 180, 180B, 180D… - [TCDS 3A17](https://openairdocs.org/tcds/3A17): Textron Aviation Inc.; names 5 of 12 models: 172RG, 175, 175B, 175C, 175A - [TCDS A-799](https://openairdocs.org/tcds/A-799): Textron Aviation Inc.; names 3 of 3 models: 170, 170A, 170B ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 38,120 (38,120 by airframe model, 0 by engine model) - Makers: Cessna 36,531, Textron 1,586, Cessna Wren 3 Models with the most aircraft: - [Cessna 172M](https://openairdocs.org/model/cessna-172m): 3,573 aircraft (airframe model) - [Cessna 172N](https://openairdocs.org/model/cessna-172n): 3,138 aircraft (airframe model) - [Cessna 182P](https://openairdocs.org/model/cessna-182p): 2,099 aircraft (airframe model) - [Cessna 172S](https://openairdocs.org/model/cessna-172s): 1,915 aircraft (airframe model) - [Cessna 172](https://openairdocs.org/model/cessna-172): 1,805 aircraft (airframe model) - [Cessna 182Q](https://openairdocs.org/model/cessna-182q): 1,565 aircraft (airframe model) - [Cessna 170B](https://openairdocs.org/model/cessna-170b): 1,300 aircraft (airframe model) - [Textron 172S](https://openairdocs.org/model/textron-172s): 1,239 aircraft (airframe model) - [Cessna 180](https://openairdocs.org/model/cessna-180): 1,177 aircraft (airframe model) - [Cessna 172P](https://openairdocs.org/model/cessna-172p): 1,111 aircraft (airframe model) - [Cessna 172K](https://openairdocs.org/model/cessna-172k): 1,026 aircraft (airframe model) - [Cessna 182T](https://openairdocs.org/model/cessna-182t): 968 aircraft (airframe model) - [Cessna 172L](https://openairdocs.org/model/cessna-172l): 857 aircraft (airframe model) - [Cessna 182A](https://openairdocs.org/model/cessna-182a): 784 aircraft (airframe model) - [Cessna 172H](https://openairdocs.org/model/cessna-172h): 780 aircraft (airframe model) - [Cessna 172G](https://openairdocs.org/model/cessna-172g): 722 aircraft (airframe model) - [Cessna 172F](https://openairdocs.org/model/cessna-172f): 717 aircraft (airframe model) - [Cessna 172R](https://openairdocs.org/model/cessna-172r): 683 aircraft (airframe model) - [Cessna 172E](https://openairdocs.org/model/cessna-172e): 617 aircraft (airframe model) - [Cessna 182S](https://openairdocs.org/model/cessna-182s): 606 aircraft (airframe model) All 64 models: https://openairdocs.org/ad/73-17-01/models.md Every aircraft: https://openairdocs.org/ad/73-17-01/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
