The cost of the TT straps was raised by Airwolf to $15,900 USD. They still have a 5 year calendar life, and require inspections at 1200 hours.

flylow-
Thanks for the update on the STC cost. I haven't been closely following the pricing since the ship I'm buying has already been converted.
True about the 5 year life and 1200 hr inspections, but the Lamiflex bearings also have a 5 year life and I've heard from other Enstrom owners that they seldom survive the full 5, so overall it sounds like an improvement to me. I've also heard (from owners) the TT straps give a smoother ride and don't get out of track, but I don't (yet) have any experience with that.

TT Straps

My experience is on 480 TT straps are no better than lamiflex, first 480 we had was on lamiflex no real issues, if set up correctly both equally as good it just comes down to cost.

MPI cost

The FAA has estimated costs for compliance with AD 2018-02-01 as follows:

Costs of Compliance

We estimate that this AD affects 323 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Inspecting the spindles takes about 15 work-hours for an estimated cost of $1,275 per helicopter and $411,825 for the U.S. fleet per inspection cycle. Replacing a cracked spindle costs $8,164 for parts and no additional work-hours. Replacing a set of three spindles that have reached their life limit takes about 14 work-hours and parts will cost $17,500 for a total cost of $18,690 per helicopter.


IF those estimates are accurate, then there's no economic case for NOT doing the TT strap STC when 1500 hrs TIS is reached. Prior to 1500 hrs TIS there's potentially 2 inspection intervals when spindles could be returned to service after the MPI at an hourly DOC increase of $2.55 and then replaced after the 3rd 500 hrs, so at least there's some options.
I feel the pain of an almost $20K expense outlay but I'm trying to look on the bright side...

Owning an Enstrom

A few months ago while I was considering various options for a personal helicopter, I ran across this clip on youtube from Kenny Keller who really likes Enstroms:

Enstrom vs. R-44

Another video from Kenny Keller comparing the Robinson R-44 to the Enstrom F-28/280. You may be surprised-

Yeah, I've flown both too, and yeah the Enstrom is a really nice and well built helicopter, but I'm willing to bet that what makes people chose that R44 time and time again, is that back seat.

The Enstrom holds three like the R66 holds five,...and like my Trans Am's back seat holds anyone with well, legs!

As for myself, a guy recently tried to talk me into switching from an R22 to an Enstrom, and my answer is always the same,...price. The view from the cockpit is the same, so why pay more?

Not quite. Look up and you'll see a fully articulated 3-blade rotorhead.

I regularly fly 3 in my Enstrom doing event rides or longer tours. We fit just fine.

I'll take the proven better safety and build of the Enstrom over an R22 any day.

Its the 12 year life that really gets me down with the Robinson, for a PPL owner that's a big cost.

Over the 18 years I've owned Enstroms the cost has been minimal compared with a Robinson - and that includes an engine rebuild and the TT strap conversion I'm about to have done. For me as a private owner it has been a cost effective, fun, safe and generally pleasurable experience.

Ps anyone want 3 Lamiflexes cheap with a year or so left on them?

SIL 0187 and TT Strap Installation

Just a heads up for those of you who may be installing the TT straps for the first time in your Enstrom. Be sure to check out Service Information Letter 0187 when you install the system. There is potential for interference between the retention pin and the U-Block. I wish this had been mentioned in the STC installation paperwork. We ran into all sorts of problems balancing the blades after the STC until we found this out.
