I’m still trying to understand why QF are running their A330-300s on cargo only runs to China and Tokyo as opposed to the 787s. I get that the -300 is preferred over the -200 because its belly has more volume. Furthermore I get that the fuel burn advantage of running a 787 on transcon cargo flights...Jump to post
Sadly if the pictures of the engine scrape damage are right the aircraft is likely to have been terminally damaged after contact with the runway. As both engines could have suffered extensive damage to the main gearboxes as on the CFM56-5B its on the bottom of the fan case. Damage gearboxes would re...Jump to post
On the Load 15 report being on the printer. Worked in one place the auto print had been selected off in the ACMS software. Found that out after investigating some FDM hard landings that had gone unreported that would have been sufficient to trigger the report 15. So even if you don’t get a report 15...Jump to post
The consequences of airlines failing is massive, think about all the staff in support industries? Direct such as ground handlers, caterers and the such. Then the indirect the ones that supply the caterers, fix the aircraft parts. Then there are the industries the transport particularly aviation indu...Jump to post
The main issues with the Trent 1000/Ten engine are with the IP section both IPC and IPT. I've not seen this mentioned much but the power offtake for the generators/gearbox is from the IP section on this engine due to the genys and believe the XWB reverts back to Roll's traditional location for power...Jump to post
Looks like PAL did a better job in the end, ok their aircraft got damaged but it was repaired and put back into service. Whereas Delta dowsed people on the ground. As for fuel, after doing plenty of fuel tank entries during maintenance I can confirm its horrible stuff and even with the use of barrie...Jump to post
Wonder if they swept the apron and taxiways of ash? If not guess they are relying on the aircraft to vacuum it up. Give it a few months if the latter is the case and there’ll probably be some unscheduled engine removals for turbine distress. Doesn’t take much ash to block cooling holes in the hot se...Jump to post
Recently the airport has just been closed due to the eruption of Taal Volcano. According to Tokyo VAAC the ash is present from SFC to FL550. So pretty high plume. Flights diverting and the airspace over Luzon now looks pretty quiet. Wonder if any aircraft were affected by ash prior to airspace being...Jump to post
Looks like a bit of rough landing of a A321 in Antayla.

Some British Airways flights earlier from Southern India were tracking over Oman then Saudi and then north from the west coast of Saudi.Jump to post
Another thing that may hamper early frames longevity is if they still have early CFMI -5A or IAE A1 engines on them. Parts for these may be running low globally and any aircraft now being scrapped that have life on internal engine parts may even be going up in value to support what remains in service.Jump to post
The 787 does have compressed air system similar to bleed air, as essentially the CACs are generating hot bleed air. Packs are pretty much the same as any other aircraft, bar the ram fan that is electrically driven rather than off a shaft on the pack. Reason for that is cooling on the ground for the...Jump to post

Likely repairable, be interesting to see if the fin copped any damage as that tail docking was close. As for who picks up the tab, if done by a third party then a good chance it’ll be their insurance picking up the bill for repairs. If its on Spirits then it’ll be solely down to the repair cost vers...Jump to post
Some here almost suggest a compressor stall is a non-event. Yes a minor recoverable one maybe so as it is unlikely to do much damage internally of the engine, but this one was slightly more than just a stall, wouldn't be surprised if the compressor is seriously affected with at minimum blade curl on...Jump to post
News articles online today are indicating a GoAir A320 Neo departed the paved surface while attempting to land a few days ago in foggy conditions. Interesting thing is the left engine also allegedly stalled (GTF) when crew chose to take the aircraft back into the air. Pictures show the off roading w...Jump to post
Interesting, that door was definitely still open for maintenance as there is that red/white safety pole/strap in place. Probably a bit more to it than just being pushed out of the hangar as surely an engineer at QF would have done a walk around before commencing a push out of a hangar, especially on...Jump to post
Possible they had the landing gear override switch selected. In which case the TAWS wouldn't say a peep. What switch? Please expand on this and why would it have been selected? Are you a qulaified 787 pilot? 787 - on the TCP you have three selections when you select GPWS along the top edge, flap ov...Jump to post
Would have a been a bit more of a conscious decision than on some other types as the gear override is not a switch. You have to go into the GPWS page on the Tuning Control Panel. The only physical switch left is the G/S Inhibit.Jump to post
The TAWS would have certainly started barking at them if they hadn’t put the gear down. Pretty impressed by the speed of the ATSB investigation being launched. Must have been lodged by the ATC. Hopefully the ATSB was able to request for the Voice and Data recordings from the EAFR before it departed ...Jump to post
The big difference between the BA and SQ ones and this is that the fire was internal to the structure. This leads to an far more intense fire once it gets going and in this case as the cargo doors were open a unlimited source of fresh air too supporting the blaze. Additionally, very difficult to fig...Jump to post
The picture above of structure is part of the pressurised fuselage area. The nose gear bay of a A380 has essentially a large fairing surrounding it. No the gear bay is structural aluminum.

The picture above of structure is part of the pressurised fuselage area. The nose gear bay of a A380 has essentially a large fairing surrounding it.

The forward doors open only when the gear is to move, then they close after the move, be it lowering or raising. The fact that they are open indicates that someone selected gear up without the locking pins in place. The main gear wouldn’t move because of the weight on them; they go sideways so woul...Jump to post
Gear doors can also be opened for maintenance as well.
As for hydraulics, the aircrafts electric pumps or a ground supply cart can be used to supply pressure without engines running.
Not the first time a aircraft has been dropped on its nose during maintenance and won’t be the last.
If they are lucky its just the nose fairing, the unpressurised section under the flight deck floor that has taken then brunt of the damage. Not sure of the clearance though on the inboard engines if the nose gear is retracted position. Perhaps resting on the engines. Also that DR1L is missing! You c...Jump to post
I'd be surprised if United is fully self-insured, especially in the US with the potential exposure to liability costs. Also, most lessors will stipulate as part of a lease agreement that Hull All Risks insurance is required to protect their interests, unless of course, United does not lease a single...Jump to post
Airlines will almost certainly all have some form of Hull All Risks insurance. This will cover the aircraft on an agreed value basis for insurable events and associated liabilities. It also covers many other things such as aircraft spares. Search for AVN1C and you will see what the basic foundation ...Jump to post
If flight and cabin crew are avail then airlines based in HKG will try to operate as scheduled whether passengers are there or not.

Does anyone have a copy of the AFM TRs as mentioned in the AD? Be interesting to know what the actual limitation is. As it only affects L102 ELAC software standard, perhaps operators can regress the modification standard of their ELACs to L101 standard to remove the AFM limitation? Whilst AIB develo...Jump to post
Likely to be the Jettison Valve stuck open and centre pumps on most. Doesn’t get operated often except for required maintenance tests.

Very few wings are not painted on commercial aircraft. The ones that may not look painted would be with coated with something like AkzoNobels aeroflex paint. It tends to look like an unpainted finish but it is definitely is not. Plastic wings and wing panels are always painted with solid colours, gr...Jump to post
Surges are not an increase in thrust.
Its when the air flow in the engine essentially reverses, poor airflow control in the compressor section.
Most definitely resulting in a reduction of thrust.
Looks like an investigation has been launched.

Started in descent. Although problems persited.
Think this Jetstar incident is a bit different to the ANA incident, this happened on descent not approach some way out from KIX. Possibly fuel icing issue perhaps maybe further affected by contaminated fuel. Fatty Acid Methyl Ester (FAME) contamination comes to mind as that affects the freezing poin...Jump to post
All airlines will have some form of Hull All Risks policy. It would typically cover the Hull (aircraft) on an agreed value basis, spares and other risks such as liabilities.

There’s another thing to possibly consider in all this, if Boeing moves and suggests airlines ground aircraft then they will also be up for the operating losses for all the airlines.

If we are talking 737s, the stall prevention is the human, stick shaker for attention getting and a resistance to up elevator via the elevator feel and centering unit from a output from the SMYD which guess what relies on AOA.

Waterbomber, with you on that, the damage does look odd, but with everything new generation you see weight taken out here and there so wouldn't be surprised if the cone was just impacted by high-velocity turbine debris and unable to withstand it.

That is the exhaust section of the engine quite clearly. Last stage of LPT (3rd), with vane segments in front of it.

What I noted from the reported is that the PIC of the flight from DPS-CGK picked up the automatic trim inputs nose down and also stated that by the third trim input the control column became too heavy for the SIC.
