| Ice age heat wave, cant complain.  |
This past Friday morning I was leaving MCO en route to LAS. I boarded and took my seat in row 8 of an A321 Sharklets. While other passengers were boarding, I hear something explode/rupture in the belly of the air craft. This took place very near to my seat, within a row or two forward or rear of me. Immediately after the loud noise, I heard what sounded like air or gas rapidly escaping a canister or pressurized container. This was maybe five or so seconds and then whatever ruptured was empty. I looked around and it was almost as if no one else heard it or cared. The FA that typically hangs between first and coach was helping someone so I didn't bring it to their attention right away. A few minutes later I noticed they stopped the general boarding. Shortly after that the pilot got the PA on and in a very vague way advised us there was a mechanical issue and the aircraft wasn't up to AA's safety standards so we were going to de-plane. Any ideas?

The flux capacitor blew a seal. Probably made in China instead of Hill Valley.... "If you’re a leader, you lead the way. Not just on the easy ones; you take the tough ones too…” – MAJ Richard D.

Therefore, as tongues of fire lick up straw and as dry grass sinks down in the flames, so their roots will decay and their flowers blow away like dust; for they have rejected the law of the Lord Almighty and spurned the word of the Holy One of Israel." - Isaiah 5:20,24 | |||

It sounds like one of the fire bottles for the cargo compartment blew. If the loaders were in there I hope they were near the door or they are going to sleep. | |||

Could have been a tire fuse, if the brakes were really heated it deflates the tire instead of blowing the tire. http://www.pprune.org/tech-log...e-plug-question.html | |||

I LOVE that picture! It's the perfect frame. "It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life – daily and hourly. Our answer must consist not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual." Viktor Frankl, Man's Search for Meaning, 1946. | |||

Some aircraft have emergency pneumatic bottles for "blowing" the gear down in the event of hydraulic failure. If someone inadvertently "pulled the handle", it could have resulted in what you experienced. And it is a bitch to clean up the mess, iinpect systems affected, replace any parts, service and test the systems. BTDT, on F-4 and F-15 aircraft.

I'm not familiar with the pack location on the AirBus but I suspect that is what it was. The pack supplies conditioned air for the interior and electronic cooling. The cooling requires compression and includes a whole host of tubes, valves, heat exchangers, and a turbine. Many of the connections are made using a high temp "rubber" coupling and clamps. The are known to blow off occasionally and sound just as you described. The sound stopping wasn't because it was empty but because the crew was alerted and "turned it off". ----------------------------------- | |||

Yeah, it could have been a pack valve or seal blowing. Was the APU running or were they still on ground conditioned air? IF the APU was not running then the packs were (99% chance) not running. I don't know what the A320 has for cargo fire suppression - like whether it is a heat-based system or a smoke-based system. Normally those systems are disarmed on the ground to prevent injury to anyone in the compartment loading stuff. If they were armed, you could toss an open bag of flour into the compartment and have the bottle go off. But then again, I'm not an Airbus guy so this is all just speculation.

Shit yeah, I think he is an A-320 guy nowadays. He could be on an ass-kicking VX trip right now, though! This and no other is the root from which a tyrant springs; when he first appears above ground he is a protector. Plato | |||

Based on all of the systems in a modern aircraft it could have been any number of failures. Suffice to say it was in a system not quickly repairable.

You did not mention if the repair was done and you reboarded soon after, or did you board another aircraft? As already mentioned, if the Auxiliary Power Unit, or APU, was running, then the PACKS, or pneumatic air cycle kit <https://en.wikipedia.org/wiki/Air_cycle_machine> likely were in use. If however when you boarded and you noticed a large yellow snake attached to the underside near where you were seated, then that was external air in use. There are two fire bottles in the cargo hold. Uncommanded discharge is highly unusual. The gear is hand cranked from the cockpit. Oxygen bottle(s) are under the cockpit and have a visible blowout disc on the aircraft skin. Aircraft Lavs work on air from bleed system. Heavy use items, Gear, Flaps, etc use 3000 psi Hydraulic systems. When on the ground and rampers are loading / unloading bags and they need to open or close cargo doors there is a PTU that some people equate to a barking dog. Easy to hear in mid cabin. <http://www.askthepilot.com/questionanswers/the-barking-dog-airbus-noises/> The four main wheels do have fuse plugs, you have to work really hard to get to those temps. Brake fans are an airline option on the Airbus 320 series. Cheers. "Freedom is a light for which many men have died in darkness." | |||

DC3S, We boarded another aircraft, they indicated it would be hours to fix the original equipment. NRA Life Member Steak: Rare. Coffee: Black. Bourbon: Neat. | |||
