Is the 414A included in the wing SID program?


There is a spar strap that is required to be added at 9000 hours for the first 200 serial numbers, and 15,000 hours for the rest. This is a BIG job, but 15,000 hours is a long time. TAS says they will only agree to do one or two of these a year, since it is so tedious. I bet Cape Air has done more of these than anyone else. There was a more recent AD for an inspection of the carry-through spar, but my impression is that is not a big deal.

https://twincessna.org/414-prospective-owners/

Edit: 9000 hours would be the first 200 414; 414As would all be 15,000 hours.

Linked article says typically 5 people with bags and full fuel.

The 414A I got to fly at Cessna wouldn't. It was typically equipped with known icing, radar, AC, and was more like 3 people with full fuel.

That math doesn't work for the one I fly either.

Mine is 4 people with full fuel and bags. It does it fine even in the hot Oklahoma summer.

People come in all sizes and packing baggage can mean something different to everyone. So one persons 5-people and bags could be same weight as 3-people with their bags.

Love the 421C. The trailing link gear is highly sought after. Simple answer to me was the geared engines.

That’s a shame, GTISO520 engines are very reliable and robust if maintained well and flown by a pilot with and IQ higher than room temperature.

Junk planes with bad maintenance and uneducated pilots created this OWT. I have 2,500 hours on two sets of GTISO520’s with no down time and never an AOG .

Maybe he was referring to total cost of ownership instead of reliability? I know you haven't had an AOG, but I know someone who was AOG with a $5k issue that only affects the geared engines and wasn't related to poor operation (starter adapter failed.)

Yes if wait you till the adapter goes? You replace them when they start to slip. Then there is no down time. The Ram VII HAS SIMILAR PROBLEMS.

Gerald,

You have had great experience with the GTISOs. Congratulations to you. I wish more pilots were as skilled and as educated as you. As most of us here, you believe you’re gods gift to aviation. I salute you Mr. GTISO 520 whisper, with out you we would all feel better about ourselves!!!!

:cheers:

Starter adapter problems are common to to 520s and 550s.

Gear box metal is GTISO specific.

For two perfectly maintained candidates, is the overhaul cost of the GTSIO-520 higher than the TIO-520? RAM has removed prices from their site, but I remember the GTSIO overhauls being quite a bit more last time I saw prices.

Ham fisted pilots create “PROP SHAFT” problems. One of my tenants has four 421C’s right next to my hangar. Like you I was cautious about 421 engines until I watched him overhauling engine after engine in his hangar. Then watching his engines on charter run reliably and safely with educated pilots. He also tears down and rebuilds the airplanes right next to me. It has been quite an educational experience for me and I am grateful.
He is the reason I did not go from my Ram VII 340 to a 414A. I bought a good 421C instead and I am very happy I did.
