PAL777 engine fire
|

Didn't actually catch fire, did it?????
|
That must be the definition of an overweight landing!

Gear seemed to be down a long time on departure? |

This was a training event that was introduced to demonstrate that at heavy weights (ie immediate return scenario), even at max power you'd be unable to hold level flight while in landing configuration while single engine. Rule of thumb "no gear down until you're going downhill" (ie descent patth without level offs). |
You’re missing the point. On the video shot from a car the aircraft appears to be 500+ feet AGL on departure with the gear still down. |

Normal gear retraction is as soon as a known, stabilized, rate of climb is achieved. For non pilots that typically confirmed prior to 50' AGL. With an engine failure, unless the plane is very light, the ability of an airliner to accelerate to get rid of flaps (reducing drag) is much tougher. Depending upon weight it might not be possible with the gear down.

BTW I take it we think this is a series of surges, rather than a fire ( I think that's the point Compass Call is making). |

What a very interesting post, sadly, as a B777 Captain I would disagree with most of it!!

It also is above landing weight if going far enough to change a few time zones or the weather. Thanks for your input cadet. |

I don't disagree with you, but I do think you might have misunderstood some of the original post. When he referred to being in the landing configuration after take off, I think he was referring to being on final after an immediate return due to an engine failure. At that point our procedure (A320) is to not extend the gear until we are on the slope, so he might have a point. |
Engine explodes in midair
|
Yet again the media gets it wrong. Doesn’t the BBC have an Aviation Correspondent? The engine didn’t “explode” - it was a surge. Even the captain knew that - it was announced to the tower after the Mayday call. See “PAL113 KLAX Engine Surge”: http://www.liveatc.net/recordings.php |
Even before the Mayday call, someone sees the event and calls it out on air. Well handled by all crew on board and on the ground. Media score Zero. Again. My concern is that this constant bad reporting leaves the reader/viewer with the exact opposite of what has happened, leaving people fearful when everything went according to procedure.
It may well be that, with aircraft problems being 'flavour of the year' there is nothing to hold them back. |
Flames were coming out of the tail pipe in short bursts which hardly counts as an engine on fire. Were the extinguishers even used or did the problem go away once the engine master was turned off and the fire button was pushed ?
The Philippines has only recently been upgraded to CAT 1 by the FAA and with the flight being ETOPS, PAL must be hoping the blame get pinned on the engine manufacture rather than their maintenance. |

The Philippines was upgraded to Cat 1 in 2014. IASA is focussed on aviation safety oversight. The rating is not affected by a single carrier incident. |
