Re-Sealing Procedure
The first option to solve a fuel leakage problem is to re-seal
the wing fuel tank compartment from the inside with Scotch
Clad 776 (refer to Chapter 51-30-04). It is not necessary to
remove existing Scotch Clad 776 prior to re-sealing. When
using Scotch Clad 776, be sure to follow the manufacturer's
precautions and directions for use for handling this material.
Refer to the applicable technical and safety data sheets.
The procedure is prepared for the use of a spray gun (flow
gun).
1 Drain both wing fuel tanks as per Chapter 12.
2 Remove the wing from the fuselage as per Chapter 57.
N O T I C E Damage to the wing possible.

two persons or supported otherwise when not in safe
vertical position.
Use cushioned supports (3) if applicable.
