3. Tape Copy Procedure Using a Fairchild Copy Recorder
A. General
(1) The copy recorder provides a convenient and rapid means to extract recorded flight data without having to remove the DFDR or its tape reel from the airplane. The copy process requires approximately 4 hours and 16 minutes and is accomplished by connecting the copy recorder to the ATE connector on the front panel of the DFDR.

(7)
Set the switches on the rear panel of the copy recorder to the following positions:
(a)
Set the FLUTTER COMP switch to the OFF position.
(b)
Set the servo reference switch to the INTERNAL SERVO REF OUTPUT position.
(8)
Set the controls on the front panel of the copy recorder to the following positions:
(a)
Set the channel 1 thru 6 INPUT LEVEL control to the full clockwise position.
(b)
Set the channel 1 thru 6 OUTPUT LEVEL control to the full clockwise position.
(c)
Set the OPERATE/CALIBRATE switch next to the INPUT LEVEL control to the OPERATE position (out position).
(d)
Set the SPEED selector switch to 1 7/8 IPS.
(9)
Close the following circuit breakers:
(a)
FLIGHT RECORDER AC
(b)
FLIGHT RECORDER DC
(10)
Put the flight recorder TEST/NORMAL switch on the P5 overhead panel to the TEST position.
(a) Push the RECORD switch and the forward tape movement switch (>) at the same time.
(11)
After approximately 4 hours and 16 minutes, set the MODE select switch to the STOP position.
(12)
Let the tape reels stop. Set the MODE select switch to the fast reverse tape movement (<<) position.
(13)
After the copy tape has been completely rewound to the left hand reel, set the MODE select switch to the STOP position.
(14)

FLIGHT RECORDER SYSTEM - ADJUSTMENT/TEST
EFFECTIVITY
Airplanes with Sundstrand Universal Flight Data Recorder (UFDR)
1. General
A. This procedure consists of both an operational and a system test of the Flight Recorder System. The operational test is a confidence test of major units only, while the system test checks the entire flight recorder system including all input parameters.
B. There are four major components that make up the flight recorder system. These components are:
(1)
Universal Flight Data Recorder (UFDR)
(2)
Accelerometer
(3)
Trip and Date Encoder
(4)
Flight Recorder Test Module
2. Operational Test - Flight Recorder System
A. Referenced procedures
(1) 24-22-0, Maintenance Practices (Apply Power)
B. Prepare for Test
(1)

NOTE: During the operational test the airplane engines should not be running.
(2)
Check that the following circuit breakers are closed:
(a)
FLT REC-AC, FLT REC-DC on P18-2.
(b)
Master Caution indicators on P6-3.
(c)
Indicator Lights Master Dimming Bus on P6-3.
