How To Pre-flight A Beech JET>>>>ANY400A

Looking for tips that go, "Above and Beyond," the std checklist items. Things that a really knowledgeable pilot might find with years of expirence.

Many thanks in advance to all who reply.

power lever gators (the rubber that keeps stuff from falling into the pedastal) needs to be intact and not worn or the airplane is down.

bonding cables under the spoilerons

top of brake calipers for leaks

plastic conduits for wires for the main gear for fraying and damage

hydraulic lines that go into the pressure switches below the reservoir (mx might try to get you to leave a rag in there for the next flight to check for drips. this is unsafe and illegal) don't even reach in to wipe them (I can't reach them anyway and I have slender long arms)

missing rings/washers on the air stairs.

push engine fire switches to see if the respective h/v and f/v valves close and check to see if the fire bottles go into arm mode (this isn't on the checklist (be careful to not blow the bottles!))

nose wheel steering pin for a frayed cable (hazard as it might cut your fingers)(puncture wounds by sharp metal are especially prone to infection)

pitot tubes for worn coating

elevator horn coating (check with control lock installed for more thorough viewing)

door seal channel for damage from door pins

move all pax seats for free movement and locking (check for shoulder harness placards, including the lav seat)

don't let them MEL both EFB's under the guise that you can have charts faxed as GOM, SOP's etc are required to be on board

all placards (exterior and interior) installed and readable

if Michelins are installed instead of Goodyears, check sidewalls for wear as they are slightly wider and often rub while spinning down in the wells shortly after gear retraction

seat belt extender placards for compatibility with seat belt systems with shoulder harnesses

O2 mask microphone function

Let's keep this going!

What's the deal, trying to get some FBO standby time?:beer:

Missing placards (interior and exterior).
Unreadable placards.
Missing stair hardware.
Small cracks on engine lip (rare).
Recent chips in fan blades.
Missing engine cowling/TR stang hardware.
Leaking hydraulic pressure switches under resevoir.
Abnormal tire wear (sidewalls) on Michelin tires.
Accumulator window too hazed to see through.
Broken safety wire on emer gear/door/brake handle.
Wrong KIND of safety wire on prior.
Burned out fuel/hyd shutoff valve lights.
Takeoff pitch trim horn doesn't sound if trim is SLIGHTLY out of the green.
Takeoff pitch trim horn does sound if trim is BARELY within green.
Aileron trims run at different speeds.
One aileron trim hesitates partway through full range.
O2 mask smoke clearing device broken.
O2 mask weak pressure for inflating halo.
O2 mask does not stay in cradle.
O2 mask mic inop.
Smoke goggles too scratched/dirty to see safely.
Smoke goggles cover(s) missing/damaged.

Any one of these will ground a Beechjet. Happy pre-flighting.

Oh yeah, and make sure to do the ENTIRE anti-ice check prior to takeoff (assuming you haven't grounded it yet) as we're getting into icing season. . .

a.k.a. h-stb fail season

 

[willNOTfly4free]

Wow, great tips ↑↑↑

Wing anti-ice air exhaust port is clear
Check for slippage on the engine inlet screws
Static and pitot drains are closed
Fire extinguisher properly charged
Bonding cable connects lower baggage door w/ fuselage intact
Cockpit trim indicator agrees w/ trim position marking on vertical stab.
Cracked static wicks can be hard to spot without a gentle tug
Drain holes under horizontal stab are clear
Non-LED rear nav lights have a short lifespan

How does one check the bonding cables under the spoilerons if performing a solo preflight?

Bonding straps

To check the spoiler bonding straps you can either spin an engine and deploy the speed brakes once you have hydro pressure. Or you can seat belt the yoke to the left/right and check them that way. Don't forget the bonding staps on the gear and on the rudder. Happy safe flying.

Aileron trims run at different speeds.
One aileron trim hesitates partway through full range.

HOLY CRAP! I just looked at my Beechjet and it doesn't even have ailerons, let alone aileron trim, I guess we're down for a while!

(Hope this didn't sound too snarky, just havin' fun with ya)

All of you ground preflight type folks...

Let's not forget about the airborne regime. This is only a couple, but I'm sure my memory will scratch up a few more as the peak travel season approaches...

Nose wheel vibration upon gear retraction is fairly common in the beechjet.

As our "new" beechjets get up to 6 and 7 thousand hours flight time, the EFC's often drop off line during flight.

Flap buzz is a real bugger in the beechjet, sometimes it happens on the climbout, but often I find it occurs during letdown.

Many times, due to the high quality interiors that are installed in Mexico, the quality of the carpeting is less than ideal. Because of this, the outflow valves often get filled up with foreign debris at an alarming rate. This will cause the cabin to bump uncomfortably during letdown, especially during large power changes.

Like I said, this is just a few, I will go over my notes and post some more at a later date!

In flight

Because you know all of our expertise factory trained mx technitions still pay fanatical attention to detail, don't forget the two degree's of roll per second when selecting flaps 10. I always prefer to hand fly it and have it trimmed out just to check. Also talking to a good friend at faa who is a mx inspector. He's pretty sure the safety wire in the airstairs and the home fabricated cable on the gear pin aren't going to fly. You can't just refabricate factory parts without a supplemental type certificate or parts manufacturing approval. Oh yeah, and I hope tsa doesn't confiscate my snap on high pressure guage so I can check the tire pressures, as most tires look flat already. More to come, stay tuned. Fly safe, Michaels counting on you making safety our Number 1 priority.

To all concerned...

I am of the opinion that this thread is an invaluable tool to any and all that fly the beechjet. As Flight Options has the largest fleet of beechjets in the world, I wonder if there is a way that we could make this invaluable information available to all of the pilots at that company who operate the beechjet? This would be very useful information for the pilots to have at their disposal. Just a thought...
