Passengers' mid-air terror
4:00AM Wednesday Jul 08, 2009
By Yvonne Tahana


Passengers on a Great Barrier Airlines flight watched in horror as a propeller came off in mid-air, smashing a window on their aircraft and ripping a door off.

A passenger's photographs show the damage done when a propeller came off the Great Barrier Airlines aircraft's engine in mid-flight.

"It was like an explosion going off inside the plane," one told the Herald yesterday.

"The propeller came off and hit the side of the plane ...

"Both propeller blades came off - the whole thing just destroyed itself. It just completely self-destructed.

"A door got ripped off and the side of the plane got smashed in - we all got covered in glass.

"There was a huge amount of debris that we were just covered in. There were chunks the size of golf***** that came back and hit you."

The passenger said the 11.30am Sunday flight to Auckland from Claris Airfield was a six-minute nightmare.

The plane made an emergency landing at Claris

The man, who did not want to be named, was one of 11, including the pilot, on board the three-engine plane.

He said the impact of the propeller, which came from the engine on the right wing, was terrifying.

Passengers noticed the Trislander engine wobbling during takeoff.

"It was just lucky there was one seat spare - that was where it hit and pushed the side of the aircraft in.

"If someone had been sitting there they would have been injured quite severely.

"Everyone remained fairly calm on the aircraft but everyone was fairly nervous of what had happened - thinking 'are we going to survive this? Is the aircraft going to break up?"'

One passenger pulled his camera out while the plane was still in the air.

"The guy I was sitting beside, he had the initiative to grab his camera out, but he was shaking so much he had some trouble taking pictures so I did it."

Two passengers needed medical treatment to remove debris from their eyes, and the man decided to catch a ferry back to Auckland rather than fly.

He was angry that the airline had appeared to downplay the situation yesterday, and also raised concerns about work he had seen engineers doing on the plane on Friday.

"We were taken out and put on another plane. As we were boarding the other plane, there were engineers working on that engine. They had the covers off ... and were doing all sorts of tests with it.

"It appears to me there was a problem there with it or whether the problem had been created by the work carried out on who knows, but it just seems a coincidence that an engine they were working on explodes two days later."

Another passenger told the Herald the incident happened quickly.

"I was really trying to assess the situation and hoping the plane would stay in the air and then we'd get back down safely."

The chief executive of Great Barrier Airlines, Gerard Rea, said the experience would have been a frightening one for those on board and he hadn't intended to downplay it. The airline would make available the results of an internal investigation.

Friday's maintenance on the plane was nothing to do with the propeller, he said.

The Transport Accident Investigation Commission is investigating.

3 engines? Was that before or after the 'incident'? :D

Yep, that would be before the incident. Aircraft is a Britten-Norman Trislander.

This is the 'before' shot...

That is an abomination!:D

Second only in ugliness to another of Britain's finest - the Bristol Brabazon! :p:D

It departed from and returned to NZGB ... not a strip I'd want to make an emergency landing on. The seal is only 9 metres wide.

Judging by the surroundings, it's not exactly a metropolis and @ 9 meters for a Trislander, how does that compare to YSSY 34L/16R for a 3fatty, er, I mean 380?

Sydney's 34L/16R is 3,962 metres X 45 metres.

The Blackburn Beverley gets my vote, followed closely by the Shorts Skyvan (the Flying Block of Flats).

On a more serious note, how fortunate were the pilot and passengers in the Trislander that they survived what must have been such a terrifying ordeal.

Great Barrier Island is only 20 minutes by air from Auckland but you literally step back 25 years when you arrive there. There is no reticulated power on the island, everyone has their own generator or solar panels. Even the navaids (http://www.flickr.com/photos/davidrnz/3400496461/) at NZGB are solar powered. The upside is that it is a quiet, remote, very beautiful place.

And remember you already step back a couple of decades when you get off the aeroplane from SYD in Auckland. So Great Barrier Island must be stuck somewhere in the mid 1950s...:D

Yep and you were number one on the list ... pipped at the post by Mr P. :)

Kind of like going to Queensland from anywhere else in Oz, ay? :D:p

This from today's NZ Herald Sideswipe column (http://www.nzherald.co.nz/sideswipe/news/article.cfm?c_id=702&objectid=10583494)

The story about the lost propeller on the Great Barrier Island Trislander reminds Hugh Ragg of a similar event in Fiji. "Some years ago, a pilot friend of mine was flying a Trislander from Savusavu to Suva when the propeller on the tail engine sheared off. There were two passengers on board, an elderly Rabi Islander and a Fijian woman. As he was over the sea, he headed back to Savusavu and told the passengers to put on their life jackets. A few minutes later, he felt a tap on his shoulder and the elderly gentleman asked, 'Shall I jump now?' The pilot managed to convince him it wasn't a parachute he was wearing, and the aircraft landed safely at Savusavu on two engines a few minutes later."

Thanks Bob. I meant, how wide is the u/c of a Trislander against 9 metres of Great Barrier Island runway relative to the 3fatty on Sydney's 45 metre runway?

Nigel C

A380 is about 14.3m for its outer main gear span on a 45m wide YSSY runway.

Trislander is about 4m on a 9m runway.

So, although the Trislander has relatively slightly less margin, it's also going a damn sight slower on the runway so hopefulluy there's more time to correct any deviations.;)
