(M) (O) May be inoperative provided:
No damage to the thrust reverser system exists which would adversely affect operation of the airplane, and
A procedure is established and used to ensure that the associated thrust reverser(s) is disabled and pinned in the stowed (forward thrust) position.
Refer to Table 1 for maintenance procedure.
Confirm that the associated (M) procedure for disabling thrust reverser(s) in the stowed position is accomplished, and
Confirm that no apparent damage to the thrust reverser system exists which would adversely affect operation of the airplane, and
Plan flight to ensure that safe landings can be made at the airports to be used with the thrust reverser(s) inoperative (INOP).
Note
Care should be exercised when advancing single reverse thrust to avoid controllability effects.

For NORDAM (Dee Howard) Clamshell Thrust Reversers, perform the following steps:
Verify that the airplane bus bars are de-energized and that no external electrical power is connected.
Open and collar the Thrust Reverser (TR) circuit breakers (Refer to Table 2).
Remove the outboard fairing from each TR.
Verify that the TR’s are stowed and latched.
On the outboard of each engine install the two latch lock pins through the latch box cover and the latch box.
Note
It may be necessary to remove the lockwire from the bolts in the latch box.
Attach the two latch lock pins with screws.
Lockwire the bolts in the latch box and route the wire over the lock pins.
Inspect visible operating mechanism for evidence of damage.
Install the outboard fairing to each TR.
Put a warning placard over the annunciators in the flight compartment reading, ‘THRUST REVERSER INOP’.
For Aeronca Cascade Thrust Reversers, perform the following steps:
Remove the inboard and outboard pneumatic latch access panels.
Note
Before the inboard access panel can be removed, the detachable panels on the engine mounting pylon, adjacent to the pneumatic latch panel, must first be removed.
At each pneumatic latch-mounted switch assembly, verify that the switch operating plunger is fully up. Insert a stop pin and push the stop pin fully home.
NOTE
The stop pin is retained by its handling loop abutting the access panel when the panel is closed.
At sub-panel DA-E open and collar circuit breaker C1 (LH system) and/or D1 (RH system).
If both systems are to be inhibited, open and collar circuit breakers C4 and D4 (3A) and E1 (5A).
Inspect visible mechanism for indications of damage.
Check that blocker doors are correctly stowed and free of damage.
Put a warning placard over the annunciators in the flight compartment reading, ‘THRUST REVERSER INOP’.
