MODIFICATION No: 7257H5201 ATA SYSTEM: 57

TITLE : WINGS - REINFORCEMEN T OF WING ACCESS PANELS

REASON

To strengthen the two inboard type 21 Super Plastic Formed (SPF) access panels

on each wing and thereby improve their resistance to penetration by tyre

debris.

This modification is only applicable to A310 aircraft equipped with type 21

access panels and introduces two new reinforced access panels (type 21R)

together with matching clamp rings to each wing.

Provision of recesses in door profile, matching lobes in door clamp ring, and

filling an existing clamp ring recess in skin panel ensures that only type

21R access panels can be installed at the inboard manholes.

ACTION

At each wing the inner wing tank is defuclled. The access panels are removed

from manhole Nos 1 and 2. A clamp ring lobe recess is filled at each manhole.

New type 21R access panels together with matching clamp rings are installed.

Electrical bonding tests and Leak tests are performed.

EFFECTIVITY

This modification is applicable by Service Bulletin on A310 aircraft MSN 378,

392, 399, 404 to 499 inclusive. A310 aircraft MSN 500 and subsequent are
