Passengers told to brace as QLink Dash 8 makes emergency landing

From Australian Aviation:A QantasLink Dash 8 carrying 64 passengers conducted a priority landing at Brisbane Airport on Thursday after reporting a malfunction within its landing gear.

The problem was later determined to be caused by a “faulty sensor” that reportedly told the pilots in the cockpit that there was a potential issue with the landing gear.

Flight QF2420 was travelling from Newcastle to Brisbane early on Thursday when the problem occurred.

The crew safely landed the aircraft on Runway 2 at 9:21am, nearly an hour later than planned after circling over Brisbane’s Moreton Bay.

Images show that the plane’s landing gear did successfully deploy, meaning the issue pertained to the cockpit’s warning signal rather than the gear itself.

The aircraft was met by emergency services on the runway, and later towed back to the terminal.
If I heard the TV report correctly, it was stated that an engine was shut down on final. I'm just wondering why.

If you have a left or right gear unsafe indication, the manufacturer recommends shutting down the associated side for obvious reasons.

landed the aircraft on Runway 2
???????


Otherwise, are there not "witness marks" or visual indicators that can be viewed from the cabin? It wasn't dark to rule out any viewing.
I don't know if it's a certification requirement or somesuch in aircraft. The F27 I flew eons ago had marks where you could visually tell if the gear was down and locked properly. The 737 has periscope type arrangements up front and mid-cabin for the same purpose.

Only the 737 classics witwiw. The ng’s have a double redundant proximity system with double redundant flight deck indications as well.

Thanks NIE. That's what I was driving at, a secondary facility that one way or another allows for independent confirmation of the gear status in the case of a primary system failure/issue.

Didn't get a go at the NG's before becoming time expired.

The Dash 8 does have a secondary gear down locked indicator, underneath a panel next to the FO seat. From memory it's a downlock verification system.

Presumably that is to prevent prop debris from penetrating the cabin or is there another obvious reason that I have missed? What is the recommendation in the case of both mains showing unsafe?

Here’s the obvious reasons:

Shutdown both engines on final!

Looking at the headline, surely this might just be newsworthy if the passengers hadn't been told to brace.

Good question. I thought BNE had RWY 1 and RWY Other 1.

Doesn't it depend on which way you're facing?

Brace, brace, brace
Stay down, stay down, stay down


Obviously the deaf video punter didn't hear or was YouTube glory more important? ​​​​​​​

Just a little correction: The NG and MAX are not equipped with this kind of system - this is only found on 100-500. Newer series got a second set of gear status indicators on the aft overhead.

I think the media reference to Runway 2 was the aircraft landed on Brisbane’s 2nd runway .. aka 19R.

olderairhead,

One can only hope that the relevant authorities throw the book at him. Yeah, I know, wishful thinking.

Recommended post this FEB 1986:



C-GPYD. The Dash 8 was seriously damaged on approach into Sault Ste Marie. Shortly after the company took delivery of the aircraft, it landed hard during a cockpit crew training flight. The hard landing caused the aircraft's landing gear to collapse, causing significant damage to the newly acquired plane. Of particular concern to the airline and to de Havilland Canada at the time was the fact that the crash caused one of the engine's propeller blades to violently break away from the engine housing. The blades penetrated the cabin wall of the aircraft, travelled through Row 2 of the aircraft interior and exited through the other side of the cabin sidewall on the opposite side. Since the aircraft was on a training flight, no passengers were on board. The flight crew escaped the aircraft without injury. The aircraft was removed from service and, after months of structural repairs and refurbishment, was returned to active service.

Never quite been happy to sit in the propeller blade row of a Dash 8, since.
