C. Inspection of the Air Inlet Flap before Deactivation
   (1) Measure the air inlet gap.
F Air Inlet Gap Measurement
NOTE: Do not apply pressure to the air inlet flap when you do the measurement.
     (a) Use the RULER - STEEL to measure the air inlet gap.
     (b) If the air inlet gap is 40 mm (1.5748 in.) or over then the air inlet is considered open.
     (c) Make sure that the Air Inlet Flap is correctly adjusted (Ref. AMM TASK 21-61-51-820-001).

     (b) FOR [28HH] (P2 RAM AIR IN ACTUATOR)
4. Procedure
Subtask 21-61-00-040-050-A
A. Deactivation of the Air Inlet Flap
   (1) Disconnect the electrical connector from the air inlet flap actuator 8HH (28HH) (Ref. AMM TASK 21-61-51-000-001).
   (2) Put the CAP-BLANKING on each disconnected electrical connector and receptacle.
   (3) Temporarily attach the loose electrical connector to the aircraft structure.
