FlyingVizsla Posted July 16, 2022 Share Posted July 16, 2022 Bogged airplane recovery at Rockhampton airport continues five days after sinking in soft ground - ABC News A Qantas spokesperson said flight QF1798, travelling into Rockhampton from Brisbane, landed normally on Monday night. But while taxiing at low speed to the parking bay the pilot "inadvertently guided the aircraft across soft ground and became stuck just before the terminal", the spokesperson said. 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 16, 2022 Share Posted July 16, 2022 A plane that size must keep on the Tarmac and even some of that may not be suitable. I doubt he or she will laugh that one off. There's 2 pilots involved also. Nev 2 Link to comment Share on other sites More sharing options...
turboplanner Posted July 16, 2022 Share Posted July 16, 2022 They appear to have guided it at somewhat of an angle to the path. Link to comment Share on other sites More sharing options...
Cosmick Posted July 16, 2022 Share Posted July 16, 2022 Maybe some large salvage airbags under the wings to lift wheels would work. Link to comment Share on other sites More sharing options...
facthunter Posted July 16, 2022 Share Posted July 16, 2022 (edited) There are jacking points. Probably no damage (so far). Nev Edited July 16, 2022 by facthunter Link to comment Share on other sites More sharing options...
onetrack Posted July 16, 2022 Share Posted July 16, 2022 This is typical of Q's management - buggering around for 8 days with "specialised aircraft lifting equipment that has to be flown in" to unbog it. The B717 has a MTOW of 49,900kgs and it's 30,617kgs empty. As it stands, it probably weighs no more than 40,000kgs, and probably a fair bit less. Get in a truck mounted 100 tonne crane, from a reputable crane operator who is skilled at lifting all types of loads, and they would wrap 4 to 6 wide flat woven slings around the strong points of the fuselage, hook them to a big spreader bar, and they would lift the aircraft straight up and out, and swing it around, and place on the taxiway. But no-o-o-o, that costs money that's got to be paid out, to an outside contractor, and Q management wouldn't entertain a thought like that. No, they'd rather lose a weeks income from the aircraft, cost themselves a fortune in internal labour costs, and freighting debogging equipment from around the country - but it avoids paying out good money!

facthunter Posted July 16, 2022 Share Posted July 16, 2022 I don't really think that would be an approved technique, structurally. As I've said, there are Jacking points DESIGNED to take the weight. You want to be able to FLY the plane out of there. Nev 1 Link to comment Share on other sites More sharing options...
onetrack Posted July 16, 2022 Share Posted July 16, 2022 Nev - Kunz lift aircraft with slings, so it's entirely feasible. Maybe slings around the wing roots, I'm sure some aircraft engineering expert would be able to supervise the lift. https://kunz-aircraft.com/aircraft-lifting/ Link to comment Share on other sites More sharing options...
facthunter Posted July 16, 2022 Share Posted July 16, 2022 The floor and some keel beams are the strongest parts. The skin's main job is to hold the pressurisation in. A truss to pick up on the jacking points would be the safest way. They are used all the time when doing retract tests and U/C servicing..

Blueadventures Posted July 16, 2022 Share Posted July 16, 2022 Reports now saying its out as of 45 minutes ago. Next question out there is how long before she fly's again. Link to comment Share on other sites More sharing options...

facthunter Posted July 16, 2022 Share Posted July 16, 2022 (edited) They probably just pulled hard on the nosewheel with the tug and now another row of seats has been fitted. Nev Edited July 16, 2022 by facthunter 1 2 Link to comment Share on other sites More sharing options...
Yenn Posted July 19, 2022 Share Posted July 19, 2022 There is not only the weight of the plane to consider, but also there is a suction on the bogged wheels. 1 Link to comment Share on other sites More sharing options...
Butch Posted July 19, 2022 Share Posted July 19, 2022 Call me dumb ! Why couldn't you dig a ramp in front of the rear wheels as there is plenty of clearance . Make a steel ramp that the aircraft can ride onto , use a tug and the planes own thrust to ease it out of the bog . I've been bogged a thousand times on the farm and once you reduce the incline and provide a solid surface the amount of effort to remove the bogged machine is minimal. But who uses common sense! 2 2 Link to comment Share on other sites More sharing options...
facthunter Posted July 19, 2022 Share Posted July 19, 2022 It was mainly the right hand one affected. The rear was down a lot (They are a stretched version) and using power of the amount needed would be a bit of a hazard to other people and may even move parts of the surface. The idea is sound though. There'd be plenty of noise at full throttle. Nev 1 1 Link to comment Share on other sites More sharing options...
Yenn Posted July 20, 2022 Share Posted July 20, 2022 Full throttle and it comes clear. Stand by for a quick acceleration, probably off the taxiway in the other direction. 2 Link to comment Share on other sites More sharing options...
turboplanner Posted July 20, 2022 Share Posted July 20, 2022 If we're talking about resourcefulness here, my take is that the rear wheels rolled off the concrete/bitumen and at their weight dropped straight down into the slop, which wasn't going to stiffen up much before the bitumen ahead of it so long ramps pushed under the wheels, or probably better, jacking each wheel using the jacking points and lowering base plates into an excavated hole up to tarmac level, then it could be towed backwards from axle level of the rear undercarriages with very little towing capacity required - perhaps a heavy truck winch for very fine control. Shouldn't have taken 5 days. 1 Link to comment Share on other sites More sharing options...
onetrack Posted July 20, 2022 Share Posted July 20, 2022 It's pretty much a standard de-bogging rule, that you're far better advised to be pulled back out of the bog, in the reverse direction that you went in. Only in rare cases does this rule not apply. 1 1 Link to comment Share on other sites More sharing options...

Flightrite Posted July 20, 2022 Share Posted July 20, 2022 Many years ago it was a circus at YMML watching the guys trying to get a stuck B727 freighter sunk on soft ground back to terra firma, took ‘em all day using anything they could find to stuff under the mains, was very amusing😂 Link to comment Share on other sites More sharing options...
pmccarthy Posted July 21, 2022 Share Posted July 21, 2022 About a dozen years ago, someone tried to pull out a bogged aircraft at Birdsville with a car by tying a rope to the prop, which bent like a banana. 1 1 Link to comment Share on other sites More sharing options...
