DL 941 757-300 gear problem

Sun Aug 07, 2022 1:43 am

https://www.youtube.com/watch?v=67iLaDJ_j5Q

Saw this on Matt Cochran's youtube channel 15 minutes after it was uploaded. Don't know if this is thread-worthy but just wanted to mention it.

The rear gear doors were extended even during the touchdown and the plane may have blown a tire.
Seems like it landed just over an hour late.

Did they shut down the runway?

If they used the alternate gear extension, the landing gear doors won't close. You can see the nose gear doors are also fully open.

Looks like the crew did a great job to me. Nice landing too. Glad everything turned out good. The gear doors are definitely down. Anyone know if any tires were blown?

In the first two minutes of the video, it looked like the right main gear was not down.

Regarding the rest of the video, it appears to me that the pilots managed the situation well and a good landing was the result. Kudos to the DL crew.

FR24 has it as N596NW, ship 5816. Also. FR24 has 5816 operating as DL859 ATL-MCO today(08/07/22)

Here are the ADS-B Exchange logs for DL 941 (LAS-ATL 08/06/2022) / N596NW B757-351 (ex NW)


Initial ATL go-around and landing on 9L:

Detailed landing speeds on Runway 9L and stopping just after Taxiway J at 19:41 EDT / 23:41 Z. Also, this link shows how much runway was left:

Around one hour later at 20:40 EDT / 00:40Z, N595NW started moving off Runway 9L and arrived at Gate A7 at 20:52 EDT / 00:52 Z:

Yes, flightRadar24 shows the next flight for N596NW is DL859 ATL-MCO at 08:10 EDT on 08/07/2022. However, Delta Flight Status is showing this flight leaving from ATL Gate T2. We will have to see if N596NW ended up being towed from A7 to T2 OR back the ATL hangars and another B757 will be used for DL859.

Yes runway was shut down while maintenance came out and changed the tire on the runway. I watched it from F tower. Then super tug towed it to the gate.

Lots of good info there. Funny enough, a B763 operated DL859 this morning while it now shows 5816 operating DL834 ATL-LAS this afternoon. Looks like it's at A16 now.

Yes, N596NW did not operate DL859 this morning (it was B763 N196DN) but instead was towed to the Delta hanger after 7AM EDT this morning. It was then towed to gate A16 just after 1PM for the planned DL834 ATL-LAS flight this afternoon (scheduled 2:02PM departure but now showing a 3:00PM EDT departure).

Couldn't have been as big an issue as it appeared in the video. She's over BHM right now. Thanks

More-likely it was indeed a "big issue" -- problems with gear extension and blown tire(s), but DL has the MRO resources, parts and expertise in-house to diagnose and repair the broken stuff, inspect the things that might have been damaged in the emergency landing, and get her back in service ricky-tick.

It blew a tire on takeoff from LAS and had a gear issue with the same side the tire blew and had to manually extend the gear

If you blew a tire on takeoff, wouldn't you return to the departure airport (or a close by alternate) to land? Continuing on a lengthy flight seems a bit much with a blown tire

No. I'd rather burn off the fuel enroute, versus landing heavy with a blown tire.

Often you wouldn’t know until the tower reported the debris on the runway. I had one blow on take-off in Denmark. Shanwick called me to pass the reported debris on the runway must have been ours. Engineer looked thru the viewing port on extension to confirm it.

I was on a flight with a blown tire on takeoff. The pilot mentioned it.
When we landed at our destination (DFW) we were met with emergency vehicles and we taxied to the gate.

This was on a Fokker 100.

IINM, aircraft with EICAS have a tire pressure monitoring system and the crew would have been alerted instantly of a tire losing all pressure?

Many years ago Northwest Airlines had a 747 blow 16 tires on takeoff from ORD to Tokyo and the air temperature was very hot at ORD. The gear was left down and the aircraft was flown to. MSP. That was Northwest's mani base and maintanance faculty. It gave the airline and airport time to prepare for the emergency landing. The aircrft landed safely and was repaired after landing. :old:

With that equipment, yes the crew would know right away. We didn’t have it and not sure how recent it is.

I'm not trying to downplay the potential severity of the situation. DL has the best tech ops in the business, just surprising how quickly they scheduled its next trip even though it changed twice before it finally departed.

The 757/767 have EICAS. I'm just not very familiar with EICAS on Boeing aircraft and haven't seen the tire monitoring page. I've seen it on Airbus. I believe that only the 737 doesn't have EICAS. The A300-600R may have had it while earlier A300 models didn't.

Good point, thank you for your comment. I was thinking more about the risk of bringing up the gear (e.g. potentially in an unknown condition which could cause debris to stop the doors from closing) in to the wheel well rather than landing weight considerations. Makes sense it would be better to land lighter and with less fuel.

Just curious, does the decision change if the departure airport is a maintenance base but the destination is not? Or said differently, is part of the decision a practical evaluation of where it is easier to repair the aircraft?

No. The runway re-opened not too long after the plane was towed off. If they did foam it, I'd bet it would've taken a lot longer to clean up.

A SDR (Service Difficulty Report) has been filed with the FAA for this incident: DALA2022080805405 (for Delta Air Lines Boeing 757-351: Registration #: N596NW Serial #: 32996)

FAA SDR #DALA2022080805405 wrote:

Difficulty Date: 08/07/2022

Problem Description: Ship 5816 -Tire/Gear- In to ATL due to the #3 tire blown on takeoff. Manual gear extension required due rt main gear not showing down with associated msg and hyd leak in the left system. Corrective Action: Replaced #3 And #4 tire assy. Replaced #7 brake line and truck tilt pressure line due to found damaged and leaking. Accomplished gear swing and no-go procedures.

Specific Part or Structure Causing Difficulty: None

The 757/767 EICAS does not have tire pressure info. I think the A320 was the first with this added to EICAS. I'm pretty sure it's not on the 737NG fleet either. If I recall the NG does have a tire gauge on the wheel but it's not really considered accurate.

Correct, we don’t have a brake temperature indicator much less a pressure readout.

Tire Pressure Monitoring System was a priced option on the 757/767 and is baseline on the 777 and 787. It’s been around for at least 25 years, if not longer.

Yes, but that has nothing to do with the ability to display tire pressure. You don’t need EICAS. Having said that, as best I can tell the 737 does not have that feature.

I know that Delta and United did not take the tire pressure monitoring system on the 777ER’s. It is easy to tell which ones don’t have the TPMS, look for the missing hubcaps on the nosewheel (and see through axle).





For some reason, old school Delta would buy all the aircraft maintenance/reliability options but keep options such as TPMS and brake temp (L-1011) out of the cockpit. I was told it was to prevent unnecessary write ups, but who knows? New Delta (Northwest) runs things differently now.
