Locked in a Hawker

Either inverter should power the fan operated venturi.

Have you checked your 900XP engine inlet lips for "spotting" yet? Look around the 12 O"clock position.

Just noticed the spotting on ours the other day. We were picking it up in BAF (they were fixing the door lock along with the 300 hour inspection). The tech rep was there and took pictures - He said that Hawker Beech is talking with Honeywell about a solution. Our inlet lips are also discolored (a bronze color), and it started happening before the a/c left LIT. They are supposedly looking into that as well.

Took our maintenance a couple times to get it right but they finally found some solution (unfortunately I wasn't in the loop what that was).

In our case, the fix was to add two washers under the head of the hexagonal lock pin receptacle. That tightens up the clearance between the handle and the receptacle enough to eliminate both problems (being locked in and being broken into).

The maintenance diagram shows a clearance limit between the door handle and the lock receptacle. I think it is .003 to .0048 inches.

I goofed and added an extra zero to my numbers, otherwise they are correct. So the recommended tolerance is .03 to .048 inches.

Looks like you made the news with this, or at least an AIN email :beer:

[/FONT] [FONT=Verdana, Arial, Helvetica, sans-serif]Hawker Pax, Crew Stuck in Door Handle Jam
[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif]A Hawker 900XP crew recently discovered after landing that a slightly out-of-tolerance closing mechanism can render the cabin door unopenable from inside the airplane, leaving the emergency hatch as the only exit. Luckily, the pilot was able to radio a lineman to grab the keys through the pilot’s side window and unlock the door handle from outside. After some investigation, the Hawker technician found that the receptacle in the door latch mechanism has a critical tolerance, and this Hawker’s receptacle needed adjustment by two added washers. “It’s a somewhat common problem that crops up on the Hawker,” the pilot told AIN. “It’s a relatively easy fix, just a matter of putting washers under the receptacle. It probably is something that Hawker pilots ought to be aware of. Hopefully mechanics and pilots will check their [Hawker] tolerance. Obviously it’s a big safety issue.” It is also a security issue, this pilot discovered, because in examining the problem he found that when the mechanism is out of tolerance, the locked door handle can be forced from outside to move and open the door. Hawker Beechcraft is investigating this problem, according to a spokesman, “but it sounds like it is a one-off incident.”[/FONT]

On the 700 I used to open the dump valve on the ground if I had the APU running for a while and had to shut the door for any reason. Seemed to do the trick.

The dump valve had an even more important and valuable feature......there have been many times I wish the Gulfstream had one

It was great for claering out the cabin when the clients were chain smoking in flight, or when the other pilot was a little gassy.uke:

Yeah!.......

.....like it was the other pilot!

If it was after eating at Freebirds Burritos then maybe so

So there I was.... on the ramp in ACK last night trying to open the door on the shiny new 900XP (300 hours) that I fly. Door handle wouldn't budge.... CEO standing in the galley waiting to get off... I was perplexed to say the least! So we called the FBO on the radio and asked them to send someone out to try to open it from the outside. He comes out, tries to open it and says "It's locked". "Not possible", said I, but we passed the keys out the window anyway in a last ditch effort, as we were running out of ideas. Turns out the door WAS LOCKED.

After investigating the situation, we determined that it is possible in our airplane to close the door with the handle locking pin extended in the locked position. Our mechanic (who closed the door for us on departure) apparently had to push slightly harder than normal, but the door handle deflects to the right (aft) enough to allow it to pass by the pin receptacle (the six sided nut) and go into the hole. We also found that the door can be opened from the outside (when locked) by pulling the handle to the right and out at the same time.

The maintenance diagram shows a clearance limit between the door handle and the lock receptacle. I think it is .003 to .0048 inches. Ours exceeds the upper limit, so the fix is to add a washer and shim the receptacle out, which hopefully will solve the issue. In the meantime, we've removed the locking pin and MEL'ed the lock.

This was certainly a first for me... Locked inside my airplane!

One other reason we don't buy Raytheon/Hawker products... As long as it takes to get a plane out of that factory you would think they could have some of the bugs worked out.

Both of our new aircraft were spot on time. Our new Hawker has been trouble free. Suit yourself though. Any new aircraft has its break in period. I have flown new Cessna's as well and they too had bugs.
