Malaysia Airlines 777 missing

Just thinking over a beer about a 777 fire back in 2007…

"The P200 ELMS (electrical load management) was removed and found to have suffered extreme heating and electrical arcing. Moveable contacts within each had been destroyed. Busbars in the vicinity of the RBTB had insulation burnt off. The failure had obviously occurred within either the RBTB or RGCB.

The 777's two components had been in situ since manufacture and had completed 43,519 flight hours (6622 cycles). They have no overhaul or inspection period stipulated.

Prior to this particular accident, Boeing had been investigating 11 similar power panel overheat events involving the P200 and P300 panels. Those 11 events all involved an ELMS II panel.

The MEC (main equipment center) has no fire extinguishing system and it is located immediately below the flight-deck. Inflight the compartment is well ventilated for cooling purposes and these flows would have acted as a fire accelerant, as per the Canadian TSB's findings on SR-111."
 
I used to have a Cessna 555AE check in 3 or 4 times a week with;

Approach Cessna triple nickel alpha eight-ball with ya decending to 8000.

Interesting. Did they issue an AD?

Under a year ago.

Docket No. FAA-2012-0597

SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. This AD was prompted by reports of in-service events related to electrical power system malfunctions resulting in damage to electrical load management system (ELMS) P200 and P300 power panels and the surrounding area. This AD requires installing enclosure trays to contain debris in certain ELMS panels, and replacing certain ELMS contactors. We are issuing this AD to prevent contactor failures, which could result in uncontained hot debris flow due to ELMS contactor breakdown, consequent smoke and heat damage to airplane structure and equipment during ground operations, and possible injuries to passengers and crew.

DATES: This AD is effective April 25, 2013. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 25, 2013.
