Most of us know how the costs involved on the PT6A engines can be when it comes to maintenance, overhauls, etc., especially on the older or higher-time engines that are used on aircraft which no longer have an appraisal value.  This all affects how to justify the expense of the required overhaul at 3600 hours (or 4100 hours on some engines).  Many of these engines are still in great condition, and that is even harder to justify the expense of an overhaul in some cases.

MORE Company, Inc. has been around now for 20 years, and more than 2100 engines are using the MORE Company, Inc. FAA approved Supplemental Type Certificates in the US and 39 foreign countries!

The MORE STC works for both private and commercial aircraft.  Without the MORE STC’s, there could be many aircraft that either fly in an un-airworthy condition, not in compliance with the FAA Type Certificate, or literally parked.  The engines using the MORE STC’s are flying, they have impeccable records keeping, and they are kept in great condition.

MORE Company, Inc. currently holds 8 FAA Supplemental Type Certificates (STC’s) for “Instructions For Continued Airworthiness” that provide an 8000 hour Time Between Overhaul (TBO) on the following Pratt & Whitney PT6A engine models:

SE000EN PT6A-21, -27, -28
SE00001EN PT6A-38, -41, -42
SE00002EN PT6A-34, -34AG, -34B, -36, -114, -114A, -116, -135, -135A
SE00003EN PT6A-20, -20A, -20B
SE00004EN PT6A-11, -11AG, -15AG, -110, -112
SE00006EN PT6A-45A, -45B, -45R
SE00010EN PT6A-25, -25A
SE00011EN PT6A-25C

What about the PT6A-60 series engines?

On August 2, 2007 MORE Company received a letter from the FAA which states, “Aircraft operators wishing to utilize the concept embodied in the MORE program to create their own inspection program must submit their requests to do so to their local Flight Standards District Office or their Principal Maintenance Inspector for approval. After FSDO/PMI approval, they may be added to air carrier Operations Specifications as an Approved Aircraft Maintenance Program (AAIP).”

On September 10, 2007, an FAA Memorandum was circulated to all FSDO’s to address the denial of the MORE STC Application for the PT6A-60 series engines. The Memo states: “We have determined that this new maintenance supplement embodies the same maintenance concept contained in the MORE Company manuals that were previously approved by the Engine Certification Office through STC’s and that it is technically acceptable as the foundation for an engine inspection program. As is normal practice, Flight Standards inspectors should consider things such as the operator’s ability to manage and perform the specified inspections, the operating environment, and aircraft usage when determining if this inspection program may be suitable for use by a particular operator.”

Since MORE Company has written the MORE “Instructions For Continued Airworthiness” for the PT6A-60 series engines, this program is available and MORE Company is now marketing this product, and providing guidance and assistance in the FSDO/PMI (or foreign equivalent) approval process. There is a contract involved between MORE Company and the operator (mainly because of the US Patent involved), with a cost of $10,000.00 per engine. Additional engines may be added to the contract (which gives the operator permission to use the MORE Company US Patent for a particular engine serial number(s)) at the cost of $10,000.00 per engine. If for some reason the approval is not granted, we will refund your money except $1,000.00 per engine.

The end result will be that an operation will have their own approved maintenance program, available for use on each PT6A-60 series engine listed in the contract. At the present time, we have been successful with FAA Approvals on aircraft based in US Puerto Rico, Illinois, and Maryland. In foreign countries, the IFCA has been approved for customers located in Peru and Guatemala.

Did you know?

For all that are tired of using the older analog version Chadwick-Helmuth 192A Vibration Analyzer to satisfy the engine vibration requirement, MORE Company worked with the FAA to create a Service Bulletin that permits the alternate use of the MicroVib II Aircraft Analyzer?  This device is digital, compact, affordable and easy to use.  For sales information, contact Dynamic Solutions Systems at 760-598-4000 or visit their website at www.dss-micro.com.

If an aircraft transfers ownership, the MORE STC’s are easily transferable.  There is a transfer form, a fee, and MORE issues a new Certificate giving the new owner permission to use the MORE Company STC- required by FAA N8110.69.

On the MORE Company website, www.morecompany.net, there is a list of maintenance facilities that have knowledge of the MORE STC’s.  If there is a facility that is not on there and would like to be, please contact MORE.

So, for all of you that know MORE, thank you for your recognition, support and continued efforts in keeping the PT6A engines ALIVE!

Journey On,
