Comments: DURING GND RUN, COMPLETE LOSS RGB OIL EX

During ground run, all oil drained from rgb. Post-op: 5” crack adjacentto output shaft seal. Service Investigation findings: crack confirmed to bedue to fatigue. Root cause of cracking could not be confirmed. No otherdiscrepancies that could have contributed to the crack were found. Crackoriginated along the radius at the intersection between the mating flange ofthe No. 16 / 17 bearing sleeve and the oil plug boss. The junction of thebearing sleeve face & the face of the oil plug boss most likely created a stressriser. BURU - source of cracking untermined, but due to fatigue and overloadat fracture surface.

Report List Hierarchy

Some recipients require an overview of all P&WC product. Some othersneed to concentrate on more details. To reach everybody’s expectations,while reducing distribution volume, we have structured reports in ahierarchical manner. 4 levels of reports are available:

1. The highest level (P&WC Engines) contains only censusinformation2. It covers all P&WC engines except Industrial &Marines, PT6T-400 gearboxes and PT6T gearboxes.

2. The second level reports engines by family. Census of thesefamilies are generally covered within the previous level issue.

3. Third level relates engines statistics by market group: it is

sometimes necessary to obtain reliability progressions on a moredetailed level. Leaving out this fact, i.e., PW120 SERIES, PW124SERIES and PW127 SERIES are already covered within a singlebook within the previous level PW100 SERIES.

4. Level 4 reports are special issues driven by the Engine Groups.Then, even if they are generally a subset of the level 3, they maycontain some additional information.

Please order books according to your need and convenience in avoidinguseless duplications.

2Reliability at this level would be meaningless.

GLOSSARY Pratt & Whitney Canada PT6T GEARBOX

Aborted Takeoff: A takeoff which has to be discontinued for anyreason.

Aircraft Active Population: Active population includes flying aircraft incurrent operation. (Includes disposition active and experimental).

Aircraft Population: Total aircraft population includes flying, new,experimental, and dormant due to storage or not reported in over15 years.

Airline: Airlines are identified as operators with Boeing 747/400 andLocheed L1011 aircraft equipped with APU’s PW901A andST6L-73.

APU: Auxiliary Power Unit.

BIF: Basic Inflight Shutdown - an inflight-shutdown which is caused bymalfunction directly basic to the engine or engine component.

BPR/O: Basic Planned Removal/Overhaul - an engine removal forscheduled maintenance, either fixed time maintenance or thatdetermined through ECTM.

BSV: Basic Shop Visit - the sum of BUR’s & BPR’s.

BUR/O: Basic Unplanned Removal/Overhaul - the removal of anengine which is caused and incapable of continued operation whilebeing operated and maintained in a manner for which it wasdesigned and the cause was not externally induced.

Commuter Class: The Commuter/Regional engine powered aircraftoperators are classified as any paying passenger carrier flying on ascheduled route.

Corporate/Utility Class: Corporate/Utility aircraft operators areclassified as any private, corporation, business, cargo, charter, andgeneral utility usage.

Damage in Transit: Engines returned for repair due to transportationdamage.

Delay: An originating flight departs later than the scheduled departuretime.

ECTM: Engine Condition Trend Monitoring - A computer programused to monitor the health of a gas turbine engine in flightconfiguration.

Engines Installed: Engines installed on aircraft includes active, new,experimental, and dormant due to storage or not reported in over15 years.

Engine Population: Current engine population includes all enginesmanufactured with the exclusion of engines that were reduced tospares or written-off.

Engine Re-shipped: New zero time engines returned to manufacturingfrom operators and OEM’s for upgrade or quality problems arere-shipped to the field and are identified with a new ship date.

Flying Engines: The sum of all engines in operation on wing excludingthose installed on dormant aircraft.

FOD: Foreign Object Damage.

Geographical Region: Indicates the country, state or province in whichan installation’s owner bases his aircraft.

Installation Class: Categorizes aircraft by classifying the operator’sprimary usage of his aircraft(airline, business, government,commuter, etc...)

Installation Code: Aircraft model.

Installation Serial: Is the aircraft serial number assigned by the OEM.

Installed Engines: The number of engines currently installed onaircraft.

Military Class: Military is identified as any installation aircraft/enginecombination being operated by military organizations regardless ofthe program.

MTBF: Is Mean Time Between Failure: A performance figure calculatedby dividing the total unit flying hours (airborne) accrued in aperiod by the number of unit failures that occurred during thesame period. Note: This is different from MEAN TIME TOFAILURE (See MTTF).



Ref: msrglosApril 5, 2004

PT6T GEARBOX Pratt & Whitney Canada GLOSSARY

MTTF: Is Mean Time To Failure. A performance figure calculated bydividing the summation of times to failure for a sample of faileditems by the number of failed items in the sample. The same itemfailing ”n” times constitutes ”n” failed items in the sample. Note:This is different from MEAN TIME BETWEEN FAILURE since noallowance is given to items that have no failed.

NIF: Non-Basic Inflight Shutdown - An inflight-shutdown other thanengine/component cause which are found to be as a result ofmaintenance or personnel error, malfunction or aircraft systems,foreign object ingestion, etc...

Not Reported over 15 Years: Engines/aircraft not reported over 15years are being placed as dormant due to the uncertainty of theirdisposition which could effect the overall estimation in total flyinghours.

NUA: Non-chargeable Unplanned part removal. i.e., Part changeoutdue to operator error, contamination, external FOD...

NUR/O: Non-Basic Unplanned Removal - an engine removal caused byexternal circumstances such as FOD, inadvertent overtorque, poorline maintenance, etc...

MRT: Monthly Running Time. Aircraft time accumulated during a onemonth period.

MSR: Monthly Summary Report. A monthly summary of the latestinformation available on Census & Reliability Data. This obsoleteterm has been replaced with .bf swissb RACR. .pf

New Engine Returned: New zero time engines returned tomanufacturing from operators, OEM’s for upgrade or qualityproblems.

OEM: Original Equipment Manufacturer.

On Condition Program: The ON CONDITION program is acomprehensive system allowing the operator to maintain hisengines on wing by performing modular inspections.

RACR: Reliability Analysis & Census Report (The current report). Aquarterly summary of the latest information available on Census &Reliability Data.

Removal Assumed: An engine is sometimes changed in the field fromone aircraft to another without a removal being reported. In thesecases an engine is assumed removed and an event recorded priorto re-installation on the other aircraft is reported.

Removal, Engine: The removal of a module or complete engine from anaircraft for repair or overhaul.

Rolling Average Rate: The number of events in a period of X monthsdivided by the engine family fleet time accumulated in the sameperiod.

Spare Engines: The total of engines new at the OEM, rentals, extras atthe operators location, and the ones on the buyers market.

TBO, Basic: Time between overhauls - The fixed time that anengine/component is permitted to operate between overhauls aspublished in Pratt & Whitney Service Bulletin.

TBO, Highest: The approved maximum fixed Time Between Removalsattained by operators based on engine overhaul sampling.

Top 10 Contributors: List in sequence the highest number of failures ofa part to the lowest (10th) in a specified calendar time period.

Total Engines Produced: The total number of engines as produced outof manufacturing, within each model series, and shipped toO.E.M.s, operators, overhaul shops, or into P&WC storage.

TRT: Total Running Time - Aircraft engine(s) time accumulated topresent date. Time is made up of hours reported + estimated hoursup to date.

TSO: Time Since Overhaul - The time accumulated since anengine/component was last overhauled.

TSV: Total Shop Visit - the sum of all engine removals for repair oroverhaul ( translates to the sum of BSV & NUR).
