Applies to Models 415C, 415CD, 415D, E, G, and F1 Series Airplanes, Serial Numbers 1 through 5714 inclusive, Except Those Airplanes Modified in Accordance with Either Ercoupe Service Memorandum No. 63 or Air Products Document No. 110. Compliance required as indicated. To prevent loss of rudder control, accomplish the following: (a) Before further flight, after the effective date of this AD, with the nosegear raised off the ground, inspect the rudder control system by checking the rudder controls from the cockpit for freedom of movement through the entire range of rudder control travel. If any restriction or impediment on the normal freedom of movement of the rudder controls is apparent, the cause thereof must be determined prior to further flight. If it is determined that the restriction or impediment is caused by binding in the rudder bellcrank at the stabilizer, before further flight, modifythe rudder bellcrank assembly in a manner prescribed in (c) of this AD. (b) If the rudder bellcrank assembly is not modified as a result of findings made during the inspection provided in (a), then it must be modified in a manner prescribed in (c) of this AD within fifty (50) hours time in service after the effective date of this AD. (c) Modify the rudder bellcrank assembly in accordance with any one of the following - (1) One of the two methods contained in Alon Service Bulletin No. 14, dated February 3, 1967; or (2) The method contained in Ercoupe Service Memorandum No. 63 (available upon request from Alon, Inc., Municipal Airport, McPherson, Kansas); or, (3) Any other method approved as equivalent by the Chief, Engineering and Manufacturing Branch, Federal Aviation Agency, Central Region. This directive effective February 11, 1967. ## Affected data sheets (2) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A-787](https://openairdocs.org/tcds/A-787): Univair Aircraft Corporation; names 5 of 8 models: F-1A, F-1, 415-D, 415-G, 415-E - [TCDS A-718](https://openairdocs.org/tcds/A-718): Univair Aircraft Corporation; names 2 of 2 models: 415-CD, 415-C ## 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: 1,105 (1,105 by airframe model, 0 by engine model) - Makers: Ercoupe 793, Engineering & Research 210, Forney 79, Erco 12, Aircoupe 10, Univair 1 Models with the most aircraft: - [Ercoupe 415-C](https://openairdocs.org/model/ercoupe-415-c): 623 aircraft (airframe model) - [Engineering & Research 415-C](https://openairdocs.org/model/engineering-research-415-c): 160 aircraft (airframe model) - [Ercoupe 415-D](https://openairdocs.org/model/ercoupe-415-d): 101 aircraft (airframe model) - [Forney F-1](https://openairdocs.org/model/forney-f-1): 50 aircraft (airframe model) - [Ercoupe 415-CD](https://openairdocs.org/model/ercoupe-415-cd): 48 aircraft (airframe model) - [Engineering & Research 415-D](https://openairdocs.org/model/engineering-research-415-d): 24 aircraft (airframe model) - [Ercoupe 415-E](https://openairdocs.org/model/ercoupe-415-e): 18 aircraft (airframe model) - [Forney 415-C](https://openairdocs.org/model/forney-415-c): 17 aircraft (airframe model) - [Engineering & Research 415-CD](https://openairdocs.org/model/engineering-research-415-cd): 16 aircraft (airframe model) - [Aircoupe F-1A](https://openairdocs.org/model/aircoupe-f-1a): 10 aircraft (airframe model) - [Forney F-1A](https://openairdocs.org/model/forney-f-1a): 8 aircraft (airframe model) - [Engineering & Research 415-E](https://openairdocs.org/model/engineering-research-415-e): 7 aircraft (airframe model) - [Erco 415-C](https://openairdocs.org/model/erco-415-c): 7 aircraft (airframe model) - [Erco 415-D](https://openairdocs.org/model/erco-415-d): 4 aircraft (airframe model) - [Engineering & Research 415-G](https://openairdocs.org/model/engineering-research-415-g): 3 aircraft (airframe model) - [Ercoupe 415-G](https://openairdocs.org/model/ercoupe-415-g): 3 aircraft (airframe model) - [Forney 415-D](https://openairdocs.org/model/forney-415-d): 2 aircraft (airframe model) - [Forney 415-CD](https://openairdocs.org/model/forney-415-cd): 1 aircraft (airframe model) - [Forney 415-E](https://openairdocs.org/model/forney-415-e): 1 aircraft (airframe model) - [Erco 415-CD](https://openairdocs.org/model/erco-415-cd): 1 aircraft (airframe model) All 21 models: https://openairdocs.org/ad/67-06-03/models.md Every aircraft: https://openairdocs.org/ad/67-06-03/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
