FUEL FILTER CLOG Warning-

This was reported at 09 occasions on our A320 fleet which was involved in Delay and even in groundings.

Five cases on A320 fleet,02 cases on A319 and and 02 cases on A321.

In all this cases,snag was rectified by replacing the fuel filter.

We would have been avoided few delays by placing Fuel filters on station like SHJ/ DXB/MCT though it is always better to comply the job of fuel sampling etc meticulously on our fleet as per approved schedule and TCs.

If not; earlier procedure of placing Filter in Hatrack may consider to be adopted.

BIRD HIT:-

Seven cases of Bird hit were reported on our fleet by the end of the last day of October 2019 whereby many flights were affected apart from expenditure incurred in transporting Men,materials and spares for retrieving the aircraft.
Details of affected aircraft are as under:-

EXO was retrieved after replacing Nose Cowl

Airlines looses million of rupees on this account which was otherwise responsibilities lie to the
airport authority.Matter must be taken up with concerned officials.

CIG at DEL on dated 31/10 withdrawn initially after reporting the snag of Auto thrust Off.During the process of rectification as per TSM snag was persisted until connector of Junction Box 407vc and 415vc were cleaned and refitted.

Ground Incidents:-
A ground Incidents of pax steps hitting the VT-SCA While getting ready for the flight damaging the Air Intake Door of APU.This was replaced at CCU and aircraft was put in service.

Each ground personnel need to be trained and sensitised about the safety while working on the aircraft or in its vicinity.Such GIs are avoidable which cost huge money to the Airlines and inconvenience to the pax.

APU serviceability:-

Serviceability of APU on our fleet in October was very good and it was almost 96 to 97%.
