Applies to All Navion Serial Numbers NAV-4-2 and up, and all Twin Navion Aircraft, Temco D-16, Temco D-16A, Dauby, Riley, and Camair 480. Compliance required within the next 50 hours' time in service after the effective date of this directive. Service experience indicates that the unsafe condition in the main and nose gear retraction links which prompted the issuance of AD's 61-12-04 and 62-14-04 cannot in all cases be detected by the inspection as required in those AD's. Therefore, the following must be accomplished: (a) Replace the main gear retraction links with revised assembly Navion P/N 143- 33165-20, Temco P/N 57001-9 or FAA approved equivalent having the longer lap welded center section that completely covers the turned down part of the end fitting. (b) Replace the nose gear retraction link with revised assembly Navion P/N 145- 34106-20, Camair P/N 1-6031 or FAA approved equivalent having the longer lap welded center section that completely covers the turned down part of the end fitting. (c) Approval of equivalent parts shall be obtained from an FAA Regional Engineering and Manufacturing Branch or Aircraft Engineering Division, as appropriate. This supersedes AD's 61-12-04 and 62-14-04. This directive effective November 1, 1963. Revised August 25, 1965. ## Affected data sheets (3) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A-782](https://openairdocs.org/tcds/A-782): Sierra Hotel Aero Inc.; names 8 of 8 models: Navion B, Navion H, Navion (Army L-17A), Navion F, Navion A (Army L-17B and L-17C), Navion D, Navion E, Navion G - [TCDS 2A1](https://openairdocs.org/tcds/2A1): American Navion Society Ltd.; names 2 of 2 models: D-16A, D-16 - [TCDS 2A2](https://openairdocs.org/tcds/2A2): Fred Garcia; names 1 of 1 models: 480 ## 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: 882 (882 by airframe model, 0 by engine model) - Makers: Ryan 359, North American 256, Navion 249, Camair 8, Temco 8, Riley 2 Models with the most aircraft: - [North American NAVION](https://openairdocs.org/model/north-american-navion): 203 aircraft (airframe model) - [Ryan NAVION](https://openairdocs.org/model/ryan-navion): 170 aircraft (airframe model) - [Ryan NAVION A](https://openairdocs.org/model/ryan-navion-a): 115 aircraft (airframe model) - [Navion NAVION A](https://openairdocs.org/model/navion-navion-a): 99 aircraft (airframe model) - [Ryan NAVION B](https://openairdocs.org/model/ryan-navion-b): 68 aircraft (airframe model) - [Navion NAVION G](https://openairdocs.org/model/navion-navion-g): 61 aircraft (airframe model) - [North American NAVION A](https://openairdocs.org/model/north-american-navion-a): 46 aircraft (airframe model) - [Navion NAVION B](https://openairdocs.org/model/navion-navion-b): 42 aircraft (airframe model) - [Navion NAVION H](https://openairdocs.org/model/navion-navion-h): 36 aircraft (airframe model) - [Camair 480](https://openairdocs.org/model/camair-480): 8 aircraft (airframe model) - [Navion NAVION F](https://openairdocs.org/model/navion-navion-f): 6 aircraft (airframe model) - [Temco D-16A](https://openairdocs.org/model/temco-d-16a): 6 aircraft (airframe model) - [Navion NAVION D](https://openairdocs.org/model/navion-navion-d): 5 aircraft (airframe model) - [North American NAVION B](https://openairdocs.org/model/north-american-navion-b): 3 aircraft (airframe model) - [Ryan NAVION G](https://openairdocs.org/model/ryan-navion-g): 3 aircraft (airframe model) - [North American NAVION F](https://openairdocs.org/model/north-american-navion-f): 2 aircraft (airframe model) - [Ryan NAVION D](https://openairdocs.org/model/ryan-navion-d): 2 aircraft (airframe model) - [Temco D-16](https://openairdocs.org/model/temco-d-16): 2 aircraft (airframe model) - [North American NAVION D](https://openairdocs.org/model/north-american-navion-d): 1 aircraft (airframe model) - [North American NAVION G](https://openairdocs.org/model/north-american-navion-g): 1 aircraft (airframe model) All 24 models: https://openairdocs.org/ad/63-21-05/models.md Every aircraft: https://openairdocs.org/ad/63-21-05/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
