Yup only way that can happen is gear selected up, hydraulics break the overcentre lock and Voila the gear she does come up.
Item 3 on the pre start check list, Gear Selected Down !!!!!!!!

ScottW - and I was standing a few feet on your right, apparently!
Good on you for posting this explanation, there have been rumours floating around about a system malfunction causing the gear retraction. Like you, my heart went out to TB, who is justifiably proud of his aeroplane. I've known this gent for many years and have great respect for both his competence and abilities.
Jaba, T28D and FTDK, you might care to reflect on quickly condemning a fellow aviator before all the facts are in....
redsnail, look again, the chock was not in the way.

I felt the same as these guys when I was emailed the vid.
Guys, you gotta remember its a rumour network, not a d1ckhead network..

First shock followed closely by disbelief and then my heart just sank for the owner.

So I guess that makes it funny, expensive - and kinda stupid!

Gooday Dora,
I did prequalify that as rumour has it, I do not know the gear lever location but it would not be the first time in history that sort thing has gone wrong, as for the chances of this electrical fault happening, that is surely rare!

I own and regularly fly a T28D the gear locks are MECHANICAL operated by a bloody big gear lever on the left of the panel, the only electrical required by the gear is the Hydraulic Actuator Solenoid which is always in on the ground or indeed any time the gear is selected down, the indication micro swithhes for the dolls eyes and the throttle retard horn and light in the handle.
The operation of the gear is completely hydraulic by sequencing valves, the down locks are overcentre struts and the uplocks are mechanical.
Emergency extension requires no Hydraulics or electrics, the bloody big gear selector operates the uplocks and the mains free fall the nose is helped by a really big spring.
So any tought that an electrical fault could retract the gear is fanciful nonsense from those whoare not familiar with the T28 systems.

This is a T28A Model - Air Force
You have a T28D Model - Navy
Not like they ever change the undercarriage for Navy ship borne aircraft is it...
However, even if he did make a mistake... he can learn from it ..seems you two can't stop being *********.

The T28D was a converted T28A with an R-1820-56S engine. (replaced the 800HP Wright). Had a strengthened airframe for light attack and attack/ training, with 2 piece canopy. At a weight of about three tonnes it is basically the same airframe sans improvements.

And just a little addendum, the Maintenance manuals for thr T28A are also the same for T28D with Supplements for armament, Power Plant, Performance ect for the D model. Structural in the main except for spar carry through beef up and 3 hard points on each wing as wellas significant doublers in the centre section, basic Electrics and Hydraulics are same.
The Undercarraige is the same on both aircraft, but the T28D has nose wheel steering. The T28 C has same U/C but the nose wheel is smaller and the propellor is different.
All T28 aircraft have no squat switch because the U/C is manual/hydraulic.
For info the P 51 T 6 also have no squat switch for same reason, I have flown both and the Flight Manual makes a big dealout of the pre start check.
And the pre start list is very short 5 items.

Dogimed, facts win discussions for your enlightenment the Navy Aircraft were T 28 C for carrier famil, though they did not operate off carriers just the land based training strips with a mix of B models for Instrument training U/C identical to the D model and the French Fennec.

I learnt to fly in pre-digital times, and don't have anything scanned from then. So I'll stick to what I've been doing in recent years.

Anyone who was there will remember it as consistently overcast, not great conditions for good photography.

T28D..
My point was rather your postings when a pilot maybe makes a mistake and you get on here telling all and sundry what he did wrong...
I'd say my guess was pretty accurate...but if it makes you feel better, I'm sure your willy is bigger than mine.
Edit for photo link.
Some T28's NOT operating from a carrier.

Absolutely right Bob Hoover did most of the T 28 test flying which included in test some limited carrier ops to prove the aircraft could operate within the ground training strips and be true to carrier ops.
There was never any catapault gear on the T 28 the dog box structure was never designed for this, so they did touch and goes to see how the dive brake could set up the power on approach.
plenty of good reading on the T 28 C at Navy Paxutent.

Interesting little repartee there though, have to admit, One Short Of A Fourex. Perhaps we all learnt something about T28 Trojans even if we will never fly them. My education on hydraulic undercarriage implications was reinforced 30 years ago watching the passengers scramble out of an Aztec on the runway, after the undercarriage collapsed on the takeoff roll. Seems after overnight maintenance the gingerbeers had left the gear handle in an up position, and the young Kiwi pilot hadn't picked it up on his Daily..?!, and had backtraced the full length of the runway just on the safety microswitch.. When the weight came off.. the prop tips bit the bitumen. Sorry no photo.. didn't have the camera handy.
