(7) Apply a fillet seal between the flame arrestor [1] (bulkhead fitting) flange and the structure
outside the tank (aft side of the rear spar) (Figure 401).
NOTE: CDCCL - Refer to the task: Airworthiness Limitation Precautions,
TASK 47-00-00-910-802, for important information on Critical Design Configuration
Control Limitations (CDCCLs).
NOTE: This is applicable to Airworthiness Limitation 47-AWL-01.
(a) Use sealant, A00767, to apply the fillet seal.

(8) Apply a fillet seal around the perimeter of the fitting (nut [3] (jam nut) and washer [2]) to the
tank wall inside the tank (forward side of the rear spar) (Figure 401).

(9) Measure the electrical bonding resistance between the first tube that mates with the flame
arrestor [1] (bulkhead fitting) and the structure inside the tank (SWPM 20-20-00).
(a) Use an intrinsically safe approved bonding meter, COM-1550, to make the measurement.
(b) Make sure the electrical bonding resistance is 0.100 ohm (100 milliohms) or less.
