Applies to Models A23-19, 19A, M19A and B19 (Serial Numbers MB-1 through MB-520); Model B19 Sport 150 (Serial Numbers MB-521 through MB-616); Models 23, A23, A23A, B23 and C23 (Serial Numbers M-1 through M-1361); Model C23 Sundowner 180 (Serial Numbers M-1362 through M-1485); Models A23-24 and A24 (Serial Numbers MA-1 through MA-368); Model A24R (Serial Numbers MC-2 through MC-95); and Models A24R and B24R Sierra 200 (Serial Numbers MC-96 through MC-180) airplanes. Compliance: Required as indicated, unless already accomplished. A) To reduce the possibility of improper or unintentional movement of the fuel selector valve, within 50 hours' time in service after the effective date of this AD, replace the existing fuel selector valve guard with a P/N 169-920001-43 or P/N 169-920000-165 as applicable to the airplane. B) To prevent binding and assure complete shutoff of the P/N 169-920000-61-127 or -131 selector valve in the "Off" position, within 50 hours' time in service after the effective date of this AD, and thereafter at each annual, progressive or 100-hour inspection interval as required by Federal Aviation Regulation 91.169, check this valve for binding and shutoff characteristics in accordance with Beechcraft Service Instruction No. 0364-289, Rev. III, or later FAA-approved revision. If the valve does not meet the criteria contained in this Service Instruction, prior to further flight, replace it with an improved selector valve, P/N 169-380086-1, in accordance with Beechcraft Service Instruction No. 0622-289 or later FAA-approved revision. The above inspections are not applicable to the P/N 169-380086-1 selector valve and may be discontinued when it is installed. C) Equivalent methods of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region, Kansas City, Missouri. This amendment becomes effective January 7, 1975. ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A1CE](https://openairdocs.org/tcds/A1CE): Textron Aviation Inc.; names 13 of 14 models: A23-24, M19A, A24R, A24, A23, A23-19, B23, B19… ## 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: 1,349 (1,349 by airframe model, 0 by engine model) - Makers: Beech 1,349 Models with the most aircraft: - [Beech C23](https://openairdocs.org/model/beech-c23): 456 aircraft (airframe model) - [Beech 23](https://openairdocs.org/model/beech-23): 147 aircraft (airframe model) - [Beech B19](https://openairdocs.org/model/beech-b19): 145 aircraft (airframe model) - [Beech A23-24](https://openairdocs.org/model/beech-a23-24): 121 aircraft (airframe model) - [Beech B24R](https://openairdocs.org/model/beech-b24r): 117 aircraft (airframe model) - [Beech A23](https://openairdocs.org/model/beech-a23): 85 aircraft (airframe model) - [Beech A23-19](https://openairdocs.org/model/beech-a23-19): 72 aircraft (airframe model) - [Beech B23](https://openairdocs.org/model/beech-b23): 62 aircraft (airframe model) - [Beech A23A](https://openairdocs.org/model/beech-a23a): 51 aircraft (airframe model) - [Beech A24R](https://openairdocs.org/model/beech-a24r): 49 aircraft (airframe model) - [Beech 19A](https://openairdocs.org/model/beech-19a): 41 aircraft (airframe model) - [Beech B-19 SPORT](https://openairdocs.org/model/beech-b-19-sport): 2 aircraft (airframe model) - [Beech C 23](https://openairdocs.org/model/beech-c-23): 1 aircraft (airframe model) All 13 models: https://openairdocs.org/ad/75-01-04/models.md Every aircraft: https://openairdocs.org/ad/75-01-04/aircraft.md Its text cites no advisory circulars or STCs. ## NTSB investigations that cite this AD (2) 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.
