Glad those gear doors/speed brakes didn't get you Patrol Pilot! Do you have the gear door delete STC? If not, would you consider it?

Purchased the gear door removal STC immediately after the second event, then had it installed at the next scheduled maintenance interval.

How the H*LL did you just post an inline photo???????? That is SWEET!

Did you notice any performance changes after the STC install?

Were the labor hour estimates accurate?

Somebody needs to design an STC whereby the main gear doors open to their "speed brake" position when you need to lose altitude without shock-cooling the engines...

Dude, I learned how in a topic you started! Making photos appear in posts

No changes at all; aerodynamics, noise, nothing.

Mine took the high end.

That sounds spooky to me!

This is an interesting discussion and take for reason to do the gear door mod. Definitely noodling on it. Thanks!

Last thing to close are the gear doors. Keep your fluid topped up. If your low on fluid they may not close We had intermittent doors not closing. Took it to a shop and they did a gear swing and said all was fine. Took off and gear doors didn't close , cycled the gear and they closed. When I got home I decided to try and top up the fluid and it was low. After topping up the doors closed every time.

I just watched a youtube video of the accident aircraft, may have been taken on the day of the accident. It was some ground ops at Whiteman. There is one view of the aft of the aircraft as it is taxiing away. The back and undercarriage of the plane look pretty dirty---may be oil, hydraulic fluid, dirt, etc. I can't tell.

Perhaps there were issues with the hydraulic system that could have been noticed earlier if the plane had been cleaned. I always try to do a post-flight inspection including getting under the plane to look for oil, hydraulic fluid, etc.

I had my gear doors fail to close one time--It turned out that I tried to retract the flaps and retract the gear at the same time. It tripped the hydraulic gear motor breaker and left the rear doors open. After resetting the breaker I was able to cycle the gear and the rear doors closed.

It would be spooky...Vlo is 140, so if you can keep your indicated at 140 or below, you really lose some altitude fast.

Have a switch like the flaps, so you can go to 1/3, 2/3, full according to your situation. If Vlo is 140, then maybe 1/3 would be 180, 2/3 160, etc.
