CAUTION: 

WHEN IT IS NECESSARY TO REMOVE THE DATA 

ACQUISITION FLIGHT RECORDER TYPE D51615-202-
XXX FOR MAINTENACE POWER MUST BE SWITCHED 

OFF AT LEAST FIVE SECONDS BEFORE THE UNIT IS 
REMOVED FROM THE AIRCRAFT. 

 

6.1 GENERAL 

The concept of On Condition (OC) maintenance applies to the 
DAFR as far as is practicable. OC is a maintenance process 

having repetitive inspections or tests to determine the 
condition of an assembly with regard to continued 

serviceability. Corrective action is taken when required by 
assembly condition. Comprehensive Built-In Test Equipment 
(BITE) is provided within the equipment which identifies any 

subsystem failures and facilitates fault finding down to 
module (circuit board) level. The BITE can be interrogated 

using Portable Replay Equipment (PRE). 

Maintenance includes periodic inspections of the DAFR and 

the Underwater Locator Beacon (ULB) and servicing and 
maintenance of the ULB. 

6.2  DAFR PERIODIC MAINTENANCE TASKS 

The DAFR periodic maintenance tasks are to be carried out at 

Pre-flight, six monthly, 12 monthly, 24 monthly and 72 
monthly intervals, or as agreed between the Operator and the 

applicable Regulatory Authority are shown in Table 5. 

The periodic maintenance tasks shown in Table 5 except CVR 

Replay and 72 monthly Inspection can be performed on 
aircraft.
