Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

All posters with their correct me if I am wrong about door stops. Next time you fly look at the entry door to the airliner. You can see the stop pads and the stop bolts, one set on the frame, and one set on the door. Watch as the door is closed. Airbus, B787 B777 the door closes then moves down to e...

Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

Self locking nuts are best used in applications where they are designed to be tightened and then not loosened (or at least not many times). If you used self locking nuts in this application, the nuts would need to be tracked individually to know when they needed replacement. If you unscrew a self l...

Re: 739 and 739 Max. Plug issue the same?

There are plug doors. The cargo door on the B737 is a plug door, as is the Equipment bay door under the fuselage. They open inward, and are held in place by air pressure. Then non-plug doors. A320 cargo doors are hinged at the top and latched at the base. Air pressure trys to open them all the time....

Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

Can I just say that there are four bolts with castellated nuts and cotter pins holding the plug closed. If the two lower bolts were fitted without nuts and pins, they would stay where they are. The bolts go through a spring loaded tube. This spring would keep the bolts in place by shear force, no nu...

Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

In the Wichita factory, the door panel should not be cut if the airline option does not require an exit door. If the airline option calls for an exit door, then proceed to cut and install the exit door accordingly. It's as simple as that! Cutting a door hole and later patching and bolting it, if th...

Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

Regarding the near impossibility of a regular door to blow away from a pressurized aircraft. I know this has been asked before, but the thread is hundreds of posts long. Would it be possible to design and build that cover in the same way a regular door would be? as in plugging harder due to cabin p...

Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

I understand there’s lots of confusion and people saying different things. A lot of it seems to just be semantics. But it is definitely not the case that the plug is bigger than the opening like doors are. At the risk of adding confusion, this isn't really true. The door plug is larger than the ope...

Re: AS1282 PDX-ONT decompression event, returned to PDX, FAA temporarily grounds 737MAX9 for inspections

I haven't seen this talked about much, I think I saw one post mention it briefly. In the NTSB B roll video starting at 01:42, you can see the investigators check a different row where it appears the supplemental oxygen bags didn't fall down and are taking photos of it, and looking up into the compa...

Re: Unconfirmed: AS1282 PDX-ONT decompression event, returned to PDX

You can see the row number in this photo, it blew out at Row 26, definitely the plugged exit. Waiting to see a photo from outside of the plane. https://twitter.com/Kyrinker/status/1743470896638300339 Looks like the bolts are still in place at the attaching points in that photo. What you can see the...

Re: Nordic Aviation - 2023

Shame. I have been to ORD with SAS once a year for 5 years, each time bringing one or more dogs back to Sweden. SAS are very good with pet dogs. You can leave them at check in at ORD, and collect them at baggage claim at ARN. No one else provides this service, and I dont fancy negotiating with CPH T...

Re: Russian man flies from CPH to LAX without ticket and passport

This isn't really that difficult: 1) Passing security You can buy a ticket online, under any name, and then check-in on your phone. With that boarding pass you will pass straight thru security. Not with SAS. Going to USA from Scandinavia you cannot check in on line. You must go to the USA desk to a...

Re: Is there a reason why leather seats are popular in the US?

I used to work as a technician on the ramp, turning around shorthaul aircraft. When we had cloth seats, I was changing wet seat covers every day. We had boxes full of them. You couldn't wash them as they needed to be fire resistant, and we never had the correct part number. Then, 30 years ago we cha...

Re: De-icing in FL

Often when the F.O. would do his or her walk around especially on an originator they would inform the Captain to Deice if needed. Yes on a small low wing aircraft. How does the FO inspect the wing on a B787? Our deice agent here has an inspection truck. They will go out and inform the crew if deici...

Re: What happened to the aircraft you had your first flight on?

I never flew as a child, no one I knew in England in the 1950/60s did. But at the age of 14 in 1964 my first flight was on 31 Apr 1964 in a RAF Wessex XR516 at Kenley airfield near Biggin Hill. Just a circuit and back. First flight in an aircraft was also RAF, 4 months later, in a Handley Page Hasti...

Re: Rolls-Royce RB211 Broken Fan Blades

Depends what he means by broken. You could have damaged blades. Erosion on the leading edge, or maybe small nicks on the trailing edge. Then you would boroscope the engine every 25hrs to check propogation. But a broken blade, and it would be hard to get the engine started. And if a blade is broken, ...

Re: DAN-AIR London TXL operations

To further clarify (or simplify maybe?), while TXL (and to a lesser extent THF) served as the West Berlin gateways, SXF served as the airport to the Capital city of East Germany, and was were Interflug was headquartered . Was TXL always bigger than THF? My first visit to Berlin was in 1972 on a BEA...

Re: DAN-AIR London TXL operations

The only new aircraft ever acquired by Dan-Air prior to its financial reconstruction in 1991 were s pair of 732's that were allocated to TXL services. They were I believe the only 732's for airline use that were delivered with supplementary fuel ranks in the hold. This permitted non stop services t...

Re: Borescope inspection of three spool engines

FOD. But if the HP6 was good, then the rest of the compressors were probably OK.

Re: Borescope inspection of three spool engines

I used to boroscope RB211 on the wing every night at Gulf Air. There is a special tool that turns the first stage IP compressor. You have to first open the VIGVs , then you can see the IP1 compressor blades through the fan. The tool is a long stick with some nylon bumpers on the end, and you twist i...

I find it hard to believe that dispatch didn't phone-patch them to MX control and that MX control didn't ask them to verify no CB's were popped, which is why I find it improbable but possible that this was similar to LOT. I used to work MX control for Fedex its been years since I did but we had no ...

The BA A320-100 had 149 seats. Out of ARN regularly for many years and I remember that with a full pax load they often reached max zero fuel weight.

I worked for a flight attendant years ago, including on the 747. We were instructed during training to NEVER open any exists over the wing and (of course) to never, ever attempt to exit on the wing. I find this quite shocking coming from trained flight attendants. Sometimes the desire to be on TikT...

Dear all, Fun fact - There is actually a possibility to interchange engines of the type GE CF6-80C2 between the 747-400 and the 767-300ER. This can be useful if you have both aircraft in your fleet and you want to use the freshest, most reliable engines on the 767 before "finishing" them ...
