The headrest may be adjusted manually by sliding the headrest up or down as required. A friction device ensures that the headrest remains in the chosen position.
The headrest ears can be adjusted manually by rotating the ears to the required position. Again, friction ensures that the ears remain in the chosen position.
C. Foodtray Deployment
Open the endbay/console armcap, and pull on the foodtray handle to rotate the table to its vertical position. The table can now be swung into its deployed position ready for use. Close the armcap.

TESTING AND FAULT ISOLATION
1.  
Proper Assembly

Proper assembly of the passenger seat will preclude the necessity for elaborate testing procedures. Complete disassembly of the seat is not usually required. Disassembly should proceed only so far as to correct malfunctions or replace damaged and worn parts. After assembly check all seat functions to ensure that each performs smoothly with no excessive binding or other evidence of faulty assembly.

2.  
Seat Back Recline Mechanism

Seat backs recline through the operation of a recline control button with pressure applied in an aft direction on the back. When the recline control button is pushed with no pressure exerted on the back, the seat should return to its full upright position. If the seat back fails to operate in the above fashion, refer to REPAIR (Page Block 6000) for corrective action. Refer to the envelope drawings in this CMM for recline operation.
On mechanical locks, check clutch engagement in the recline lock by placing the seat back in the upright position and applying pressure in an aft direction. If the seat back reclines slightly and a click is audible, refer to REPAIR (Page Block 6000).
3.  
Breakover Seat backs are locked out from breakover by the use of a nut and bolt.

4.  
Seat Attachment to Aircraft

The seat assemblies should lock securely to the floor track at the lock mechanisms and studs at the bottom of the leg assemblies. If the lock mechanisms or studs do not lock firmly into the floor tracks, refer to FITS AND CLEARANCES (Page Block 8000).

5.  
Fault Isolation Table 1001 consists of three columns:

A. FAULT - Defines the problem.
B. PROBABLE CAUSE AND FAULT ISOLATION - Defines the most likely cause of the problem.
C. CORRECTIVE ACTION - Provides the corrective action to be taken in the order that would most likely correct the problem.
