Plane crash caught on video from inside

Post by Spinner200 »

A passenger was filming as the classic Convair’s left engine developed a major problem just after takeoff in South Africa last week. The plane crashed moments later killing one crew member. The rest of the passengers and crew on board survived.

Can’t maintain altitude on one engine? Is that normal for a Convair?

I don't know much about those planes but the prop is still going, if it's not producing power those are some pretty big planks and drag.

I'm assuming those props feather? The engine wasn't shut down until it hit the ground from the looks of it.

Fuel line broke causing ghe initial power loss and the resulting fire damaged the oil system that in turn prevented the prop from feathering. This is the Achilles heel of hydromatic props - they need oil to feather. A few DC-3's have crashed for the same reason.

Or its own dedicated hydraulic system. Had a prop runaway once and we feathered very quickly before even slowing down as we were supposed to do. The remaining hydraulic fluid did feather the prop very slowly(because not much fluid was left) but it did actually feather. Proper technique?.....I suppose only because it worked.

The Convair was at a fairly high density altitude on a warm day with a load on board and fairly low level. He did appear to be able to climb somewhat though and didn't crash for a long time. Performance obviously was marginal. I did see the video from inside the aircraft and without knowing the circumstances of the upcoming terrain or other reasoning on their part, the thought crossed my mind when I saw the aircraft turning was....if possible, keep those wings level. He subsequently got closer to the ground and crashed within a minute. Then again, a fire in the wing area can lead to a complete failure. One might consider just landing in a field(if possible) if wing failure is a concern as was done here.....

Why were there so many people on board for a test flight?

The aircraft had been donated by the owner, Rovos Air, to the Dutch aviation theme park Aviodrome. It carried the colour scheme of the former Dutch airline Martin's Air Charter (later renamed Martinair) and was to be ferried to the Netherlands with an expected arrival at Lelystad Airport on July 23, 2018. The accident flight was the final test flight before the planned start of the ferry flight on July 12.

"Test flight" term being used loosely? Perhaps more of a promotional farewell flight?

That's why we just went for the button when there was a power loss -- confirm and punch it out even it it was still making some power - the engine quit when it finished feathering anyway. Having said that maybe the crew was counting on the autofeather system which would lead them down the path described -- like everything else here there is a lack of information and speculation is just so much pissing into the wind but if in fact these facts are as speculated it does re-enforce that regardless of SOP's sometimes a pilot's best way of survival might take system knowledge and ability to adapt and react to save his ass, especially in "vintage" aircraft. 340/440 we great aircraft but the only true 2 fisted aircraft I ever flew, yup they could be a handful.

AvHerald added some stuff (unfortunately not highlighted):

On Aug 11th 2018 South Africa's CAA released their preliminary report stating that a camera had been installed in the cockpit (GOPRO). The cockpit was occupied by the captain, a first officer and the Licensed Aircraft Maintenance Engineer (LAME) conducting the final checks for the flight to the Netherlands, all three had also participated in the ferry flight of another CVLP to Australia two years earlier.

Pilanesberg Aerodrome (ed: intended destination)was closed for fixed wing aircraft due to runway maintenance. A related NOTAM was unknown to crew and staff at Wonderboom airport, who accepted the flight plan and issued takeoff clearance.

At about 50 KIAS in the takeoff run the captain commented the manifold pressure was low. After rotation and becoming airborne, one of the passengers - the assistant to the LAME - went to the cockpit and told the crew the left hand engine was on fire. The aircraft continued to climb at about 600-700 fpm until reaching about 800 feet AGL, then began to lose height. The aircraft continued with the left engine fire, the engine fire checklist was never executed and the crew never attempted to extinguish the fire, the engine fire extinguishing system was never activated. The left engine RPM was fluctuating, the engine fire master caution activated and an audible alarm sounded. The control wheel was deflected to the right, the captain commented the ailerons had been lost and requested the first officer to apply rudder. The GOPRO also revealed that the crew was not sure whether they had retracted their landing gear. In addition, crew and LAME were asking each other which engine was on fire although they had been told by the LAME's assistant. At no time the pilots or LAME discussed or attempted the fire drill for the left hand engine, which would have included feathering the propeller, pull the T-Handle to off to shut off all fluids, close the heat source valves, close the cowl doors, place the fuel shut off valve to CLOSED, turn off the fuel boost pump, operate the appropriate fire switch and if needed operate the alternative fire switch. The aircraft lost height, contacted a number of wires parallel to Sakabuka Street just north of the industrial complex, the aircraft impacted, two vehicles and the industrial complex.

Ground witnesses observed and collected melted metal debris, that fell off the aircraft while it remained airborne.

The SACAA reported the inflight left engine fire consumed parts of the left wing structure, the aircraft was destroyed by impact forces, the post impact fire damaged the right main gear and engine. In addition the power lines, the two vehicles and the industrial complex sustained damage.

The SACAA wrote: "Initial on-site investigation identified that the fire was most intense in the left engine. Soot, glazing and heat signatures were evident on a number of electrical, air, oil and hydraulic supply lines. An external fire had developed in the lower left region of the left engine nacelle. Airframe fire damage was found on the aircraft’s left wing rear spar and the exhaust area. The right engine fire was post-impact and was observed after the crash."
