P-51 nice landing…………..

used lots and lots of foam…pity….she is a lovely aircraft…not flying yet….pilot a credit

Latest news in here.. 😀

The video shows the propeller still spinning on landing so the engine was running when it came to a abrupt halt won’t this have damaged the engine or the reduction gear? or was the engine stopped before the last few seconds would the props still spin?

The prop stopped very quickly so I assume it was not under power. The pilot no doubt was able to switch off and cut the fuel, but did not have time to feather the prop, so it was still being driven round by the airflow.
Still expensive in the engine/reduction gear and possibly a bent airframe ?
A very quick way for the passenger to dye his pants a fetching shade of light brown.

Great Video.

More to do with an abrupt contact with the ground I suspect.

but did not have time to feather the prop

The propeller on the P-51 does not feather.

Definitely shockloaded, yes!
The engine has to be checked for runout and reduction gear casing damage. An aircraft with wooden blades is far more likely to get away without damage than these alloy types.
I would be surprised if the repairs to this plane are not detailed somewhere on the internet.

An update on progress is on their website!

Interesting to note the time the aircraft took to come to a halt…9 seconds. Must seem like hours to the occupants, and I’m sure the good people in Hollywood could make a crash landing last a couple of minutes at least!

Yes ,whilst also finding the only fuel bowser on the airfield via 3 trees and a WAAF on a bike 🙂
In the link above this was also posted
“December 09.New instrument panel designed and cut. New nav. pack purchased.”
Was the cockpit damaged or is this work that was planned anyway and being done now?
Hopefully flying again next year, good news 🙂

Umm post number 3…Ahhh stuff it here is the post…
“BOB has its wings off and stripped bare of ALL components. And 50% through paint stripping.
Fuel tanks out.
Wing stress panels stripped inspected and painted.
New tank liners being made.
New pipes are being made and Hyd systems overhauled. All wing hardware replaced.
Every Magnesium castings changed in the aircraft.
Wheel wells and Gun bays will be restored.
Drop tank plumbing restored.
98% of the castings have been purchased new and will be cracked checked before installation.
New seats have been made and tested which has been a huge and $$$$ project by itself!
New avionics are being purchased and cockpit and passenger cabin layout and canopy fresh air system designed and installed.
Prop is back from overhaul.
Spinner repaired.
Wiring loom being done now.
Fin and Horizontal stab stripped. Trim drives being overhauled.
Gear doors apart ,inspected and rebuilt.
Dog Box and scoop apart and tooling being made.
At the same time a Cessna 180 going together after total rebuild!
And ongoing maintenance of customers aircraft and Merlin projects!!
It has been busy for BOB and the crew with only 52 weekends in a year!!!!
I will get some Pics and post.”

Can’t see on the list or the web page the damage to the engine any ideas?

Also some very nice photo’s on there that engine test truck from ww2 what a nice piece on it’s own what do we use any pics?

Shame with the mustangs in this country there is no pleasure flights, or is there?

Every flight I have had in a Mustang has been a pleasure…

Interesting piece of film… At a guess the engine would need to be pulled apart, checked dimensionally and for cracks, twists etc not a quick task by any means… depending on the number of hours the engine has done it may be best to overhaul it fully…

No problem! Mostly just relaying other’s knowledge – correctly I hope.

A couple of clarifications.

When interviews for the evening news (‘aeroplane crashes everybody dies’ type report) the passenger was incredibly positive, gave the team and pilot a great thumbs up, thought it was a brilliant experience (failed to do the ‘I thought I was going to die’ bit as req. by news) said it was the bee’s knees and will be back! Indefatigable. Coupled with the pilot’s great work, what could have been a bad PR day for the vintage scene was put over to the public very well.

It’s a Commonwealth Aircraft Corporation CA-18 Mk.21 Mustang (CAC Mustang for short) not a p-51D. The P-51D being the USAAF designation for the US built examples. This is Australian built, RAAF used, never served with the US. It was serialled A68 (the RAAF Mustang prefix) -104 in RAAF service, which it still wears.

The owner has taken the opportunity to undertake a through rebuild as the aircraft is already down for service as a result of the forced landing. The actual damage was as minimal as could be hoped, and the aircraft could have been restored to flight within weeks, given a new engine, prop set, rad, dogbox, flaps, doors and parts. Expensive, and in Mustang parts today, wasteful. The longer route was chosen.

The owner has a certified Merlin overhaul facility. IIRC – and I may be wrong – the team had a spare engine ready to go in. The test truck is a postwar – 1950s(?) machine.

From someone better qualified than me regarding the sequence of events. “…failure of one of the “Clam Shell” inner Main Landing Gear (MLG) doors prevented the MLG from being lowered. There is an emergency procedure to lower the gear; however due to the way the RH inner door failed, this prevented this procedure from being enacted.

Despite repeated attempts by the pilot, including inverted negative G manoeuvres, to de-pressurise the main hydraulic system thereby unlatching the “Clam Shell” inner doors, he was unable to do so. With the Clam Shell doors unlatched, the pilot would then normally select “MLG Down” and the gear will free fall and lock into place. Obviously this did not take place.”

IIRC, the failure was caused by a CAC magnesium ally uplock casting for the clam shell door failing. NAV used aluminum alloy. I believe (Mustang operators?) a tech advisory was sent out after the part failure. Those with ‘NAA’ Mustangs actually built in Australia might like to look further than their paperwork – f’rinstance at the metal of the part.

Post accident (early) assessment indicated that the following would be needed:
“Engine bulk strip / overhaul
New prop
New radiator scoop and associated equipment,
New radiator scoop support structure (called the “Dog Box”),
RH flap rebuild,
LH flap rebuild,
RH Clam Shell door rebuild.
NDI inspections of structure, etc.”

The video was compiled and put up by Victoria CFA who provide fire cover to Point Cook:

CFA (Country Fire Authority) in Victoria, Australia, is one of the largest volunteer-based emergency management organisations in the world. As well as being one of the main agencies involved in bushfire fighting the agency provides emergency services to outer Melbourne and other major residential areas and major industries.

CFA has 58,856 volunteers and 1,398 paid firefighters and staff.

Thanks mate… 😀

JDK. Thank you interesting read.
