Early in the morning, we were dispatching a B737-400, with registration 9M-MMB after completing an A4 Check with AD/SB Modification. Initial supposedly 3 days check has been prolonged due to unforeseen reason, however, by the end of the day, each of us was glad as the aircraft soared high into the sky in a safe and soundly manner.
Phew~ Besides the A4 check packages, one of the major tasks that I had involved was the replacement of the Leading Edge Flaps and Slats Proximity Sensors. Basically, these switches provide positional indication to the pilots in the cockpit, whether, the Flaps/Slats are in the extend/retract position. Total of 8 sensors at each side of the wing were removed and replaced with new S/N complying with the AD/SB instruction. It was a first time experience for me; rather tough due to limited access area, but, eventually I managed to get the hang of it with some helps from my fellow colleagues. I was very grateful to have the opportunity to do this task, as, from what I heard through my Technician, the next aircraft coming in for similar check will not be doing this modification again due to time constraint. This task has been withdrawn from the check packages. Haha :)

Here are the pictures, enjoy!
9M-MMB on the tarmac, prior to departure.The guy on the headset was communicating
with the Pilots in the cockpit.
From far end, some maintenance crews
were doing pre-departure check underneath the aircraft's lower fuselage.
Probably, they were checking if the
Thrust Reversal Bypass Pins have been removed or otherwise.
For your information, if these bypass pins were not removed,
the Thrust Reversal of the Engines
will not be able deployed once selected.
Ouch!
Remember this guy?He was the person on headset
in the previous picture,
introducing, Iskandar
who works as Mechanical Trainee.
Bon Voyage MMB!
Took off to KLIA at 0900 hours ...
Have a safe flight there :)
Will be going on leave next week
for Chinese New Year ...
How's your CNY preparation so far?
See ya,
