Malaysian Airlines MH370 Preliminary Reports

WPTV Malaysia Airlines Flight 370 generic_1394973028231_3475267_ver1.0_640_480There has been an immense amount of interest in the case of the missing Malaysian Airlines MH370.  The preliminary ICAO reports have now been released and AEA is making these available to allow interested people to read and to try and gain an understanding to the events and actions related of this missing flight.

The reports are listed below and are available for download:


mh370-preliminary-report– ICAO Preliminary report
mh370-maps– Maps of the theorised flight
mh370-actions-taken-between-0138-and-0614– Schedule of actions/events taking by authorities to communicate with MH370
mh370-cargo-manifest-and-airway-bill– Cargo manifest if the missing plane 

It is interesting to note the actual amount of lithium batteries that were being carried on this flight as freight – (2453 kgs).  For those that don’t know, there are a number of regulations involved with the transit and storage of lithium batteries.  This is due to the volatility of these units.  It is also interesting to note the sequence of events as outlined in the action schedule.  There seems to be an increased amount of time involved before authorities were acting on the disappearance. 

Aviation English Academy is making these ICAO reports available for personal interpretation and open discussion.   Please use the comments section below to share your thoughts and views.






  1. This is very interesting. Is it possible for the batteries to start a fire? I didn’t know about them. Thank you.

  2. Do you think they will find it? A real mystery.

  3. I would like to know if the batteries were packed properly. It only takes one battery to start a fire and when one starts then they all go up. Plus, there will also be some toxic fumes coming from this smouldering or fire too. This could’ve knocked the crew and pax out.

    This plane will never be found. The governments know where it is but they won’t tell us.

  5. I am still puzzled as to why they don’t have real time monitoring and trekking on these planes. Everything else is being monitored – trucks, buses, taxis, armoured trucks. Why not planes? The technology is there.

  6. Thank you for this.

  7. I have always been suspicious of the Malaysians. Did anyone notice the front page of the government report misspells the name of the flag carrier.

  8. The risk posed by lithium-based batteries is, of course, fire. A fire can be triggered by several mechanisms, one being physical damage to the casing or the innards.

    Most lithium-based batteries have a venting valve which opens when the internal pressure exceeds some threshold value above the ambient pressure. I believe the pressure differential which triggers the vent is somewhere between two or three atmospheres. The purpose of the valve is to allow gases produced by a fire inside the battery to escape, preventing an explosion which would make a bad situation even worse.

    The difference between cabin/cargo hold pressure at sea level and FL350 is a little less than one atmosphere. In normal flight, it would be impossible for the pressure differential across the wall of a battery to ever exceed one atmosphere. Even in the event of a sudden decompression, the pressure differential would not exceed one atmosphere, and the venting valve would not open.

    There is, however, another factor which needs to be taken into account. The rate of change in the pressure differential may produce unexpected results. A sudden reduction in the ambient pressure in the cargo hold, not equalized by an open venting valve, could cause the battery to swell. Sudden swelling could cause the internal components of the battery to shift relative to one another, possibly leading to physical damage and resulting in a fire.

    If this sequence took place on MH370, then decompression would have led to a fire, rather than the other way around. Two events usually assumed to be unrelated would both have taken place.

  9. I am surprised that they are allowed to carry 2 tonnes of batteries as freight on a commercial flight. Wow – that makes me worry now.

  10. didn’t some company say they found it near India?

  11. No that was or is hoax. They are trying to get publicity. Don’t know why.

  12. Since the preliminary report is based on the few know facts at this time, however, no mention was made of the amount of fuel on board when departing from KUL.

    A quantity of 49.100 kg. / 108.000 lb. was apparently released by MAS to the press a while ago (March 21) yet no mention of these figures in this report (dated April 9).
