BELLANCA 7GCBC SDR # 20040512005
Aft Wing Spar Lower Stiffeners Chafed
This particular aircraft is retrofitted with metal spar wings. Attached between the aft wing spar and aft strut attachment point are three foot stiffeners. As a result, there is minimal clearance between the wing fabric and the stiffeners.
During flight, the inspection access metal cover clips vibrated, causing damage to the stiffener. Additionally, the turbulence absorbed by the aft struts further aggravates chafing to the stiffener.
The submitter recommends using a two-clip inspection hole cover rather than the four-clip type, and repositioning the clips may also reduce chafing damage. Indexing and labelling the fabric cover and wing may be advisable.
