Applies to: MODEL SERIAL NUMBER 7 ECA 1126-76 thru 1173-76 7GCAA 324-76 thru 332-76 7GCBC 887-76 thru 942-76 7KCAB 551-76 thru 584-76 8KCAB 219-76 thru 265-76 8GCBC 188-76 thru 228-76 And all previous serial numbered airplanes in which the adjustable front seat has been installed per Bellanca Kit #252. Compliance required within the next 10 hours' time in service after the effective date of this AD, unless already accomplished. To detect permanent deformation and/or cracks in the lower frame side tubes on the adjustable front seat, accomplish the following: a. Inspect the left and right side lower seat frame side tubes for evidence of cracks and/or permanent deformation in an area just forward of the side brace and side tube junction. A permanent upward bow in the side tube at this junction is evidence of permanent deformation. The area can best be inspected after removal of theseat cushion. b. If cracks and/or permanent deformation are found, repair per AC 43.13-1 and install Bellanca Kit #253, or replace the seat frame with a new reinforced seat frame P/N 7-1513, before further flight. c. If cracks and/or permanent deformation are not found, install Bellanca Kit #253 within the next 20 hours' time in service after the effective date of this AD. Bellanca Service Letter #C-125 dated May 19, 1976 pertains to this subject. This amendment becomes effective November 2, 1976. ## Affected data sheets (2) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A-759](https://openairdocs.org/tcds/A-759): American Champion Aircraft Corp.; names 4 of 22 models: 7KCAB, 7GCAA, 7GCBC, 7ECA - [TCDS A21CE](https://openairdocs.org/tcds/A21CE): American Champion Aircraft Corp.; names 2 of 2 models: 8GCBC, 8KCAB ## 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: 3,626 (3,626 by airframe model, 0 by engine model) - Makers: Bellanca 1,735, American Champion 1,056, Champion 834, Aeronca 1 Models with the most aircraft: - [Bellanca 7GCBC](https://openairdocs.org/model/bellanca-7gcbc): 487 aircraft (airframe model) - [American Champion 8KCAB](https://openairdocs.org/model/american-champion-8kcab): 449 aircraft (airframe model) - [Champion 7ECA](https://openairdocs.org/model/champion-7eca): 419 aircraft (airframe model) - [Bellanca 8KCAB](https://openairdocs.org/model/bellanca-8kcab): 371 aircraft (airframe model) - [Bellanca 7ECA](https://openairdocs.org/model/bellanca-7eca): 347 aircraft (airframe model) - [American Champion 7GCBC](https://openairdocs.org/model/american-champion-7gcbc): 232 aircraft (airframe model) - [Bellanca 7KCAB](https://openairdocs.org/model/bellanca-7kcab): 230 aircraft (airframe model) - [American Champion 8GCBC](https://openairdocs.org/model/american-champion-8gcbc): 218 aircraft (airframe model) - [Bellanca 8GCBC](https://openairdocs.org/model/bellanca-8gcbc): 182 aircraft (airframe model) - [Champion 7KCAB](https://openairdocs.org/model/champion-7kcab): 151 aircraft (airframe model) - [Champion 7GCBC](https://openairdocs.org/model/champion-7gcbc): 144 aircraft (airframe model) - [American Champion 7GCAA](https://openairdocs.org/model/american-champion-7gcaa): 119 aircraft (airframe model) - [Bellanca 7GCAA](https://openairdocs.org/model/bellanca-7gcaa): 118 aircraft (airframe model) - [Champion 7GCAA](https://openairdocs.org/model/champion-7gcaa): 114 aircraft (airframe model) - [American Champion 7ECA](https://openairdocs.org/model/american-champion-7eca): 38 aircraft (airframe model) - [Champion 8KCAB](https://openairdocs.org/model/champion-8kcab): 5 aircraft (airframe model) - [Aeronca 7GCBC](https://openairdocs.org/model/aeronca-7gcbc): 1 aircraft (airframe model) - [Champion 7GCAA (CONV)](https://openairdocs.org/model/champion-7gcaa-conv): 1 aircraft (airframe model) All 19 models: https://openairdocs.org/ad/76-22-01/models.md Every aircraft: https://openairdocs.org/ad/76-22-01/aircraft.md ## Related documents - [AC 43.13-1B CHG 1 Ed Update](https://openairdocs.org/ac/43.13-1): Acceptable Methods, Techniques, and Practices—Aircraft Inspection and Repair.
