necessary; and
WHEREAS the estimated cost for the turbine repair is $350,000; and
WHEREAS the funding for this mandated repair is available from the General Fund Sheriff Aviation
assigned fund balance; and

the General Fund Sheriff Aviation assigned fund balance; and
WHEREAS this has been through the County Executive review process.
NOW THEREFORE BE IT RESOLVED that the Oakland County Board of Commissioners authorizes the
use of the General Fund Sheriff Aviation assigned fund balance to reimburse the Sheriff's Budget for
repair for Air 2 at the estimated cost of $350,000.

Motion carried unanimously on a roll call vote with Tietz absent.
To Whom It May Concern,
The Oakland County Sheriffs Office operates two Airbus H-125 (AS-350b2) helicopters. The vast
majority of maintenance is performed by mechanic(s) at Bijan Aviation located at the Ann Arbor,
Michigan airport.
Recently a Federal Aviation Administrative Airworthiness Directive (AD) was issued requiring the
replacement of a component in the one of our aircrafts engines. This is a NO CHOICE event and its
requirement is mandatory in order to maintain the aircrafts airworthiness certificate. Although the
engine manufacturer is covering the costs of most of the repairs and replacement there were other
mandated upgrades/repairs that they are not covering. Furthermore, the required repairs have to be
performed by representatives of SAFRAN/TURBO-MECA- the engines manufacturer. Bijan cannot
perform the repairs. Bijan can and did, however, remove the engine and made it much easier for the
other agents to perform the repairs.
At the end of May the aircraft reached its hourly time in service limit of 5,450 hours; that's to say the
cumulative time in service limit before the aforementioned repairs take place. The aircraft was
delivered to Bijan and the necessary preparations were made in order to start the work in question.
Representatives from Turbo-Meca arrived and started the process. While performing the work, they
are required to inspect the engine and report any abnormalities etc. By and large, the engine was
without issues. It was discovered, however, that one of the turbines was scored/damaged. The
particular turbine is the most important in the series of compressor wheels. This wheel is traveling in
an excess of 58,000 RPM and produces the power from the engine. It, needless to say, is a critical
component and suffers the most stress.
The engine, a 1D1, The Arriel 1 features a simple design, centered around five modules for easy
maintenance. It comprises a single-stage axial compressor, a single-stage centrifugal compressor, a
two-stage gas generator turbine and a single-stage power turbine. It has a total time in service of
5440 hours. It had a complete overhaul at 3,700 hours. It is about 1/2 way through its life time before
another over haul is due.
The damage in question lies in the number 3 module. Accordingly, this must be repaired before the
engine is reassembled and authorized to be placed back into service.
Although the OCSO has a number of options relating to the repair/replacement of the items in
question those options should be predicated on sound fiduciary decisions AND getting the most out
of the dollars we spend. The Aviation Unit is completely confident that the ONLY option is to acquire
rebuilt components from a vendor outside the scope of the engine manufacturer. Not only will this
save approximately $30,000.00, those parts are readily available and have been reserved, via NET
30 days. If this window closes, it's entirely possible; in fact probable that the OCSO will not enjoy
those saving(s). Needless to say this will delay the repairs and the aircraft will be, quite honestly,
unnecessarily grounded for an extended period of time. The cost of a complete engine overhaul is
finically problematic as the engine has 1900 cumulative flight hours remaining before it's required.
Furthermore the recent inspection, although not as thorough as once conducted at an overhaul,
revealed no damage other than the instant, It makes very little sense to perform a complete engine
overhaul, either strategically or otherwise.
In short- a perfect storm developed and no one person or persons could have foreseen the events
that took place. We should feel fortunate that the damage was discovered, even by happenstance,
as the resultant could have been catastrophic both in terms of equipment and danger to crew
members, not to mention the public in general.
Should anyone have any questions or concerns, please do not hesitate to reach out to me.
Very Truly Yours,
William Christensen
Senior Pilot, OCSO Aviation Unit
