Large Commercial Aircraft

United States Aircraft Operator MD-80 Aircraft
Thrust Reversers Accumulator System (Two per Aircraft)
Fleet Size   67 Aircraft
Hourly Utilization   2200 hour/year/aircraft
Average Accumulator overhaul cost   $2413.00
Average Repair Cost   $367.00
Pre-charge verification performed every 14 Days   1.5 Manhours @ $47.00/hour
Replacement of one Accumulator   2 Manhours @ $47.00/hour
Fleet Failure Rate   33 Failures/12 month period
Fleet Hours per 12 month period   147,400 Hours
Mean Time Between Failures (MTBF)   8933 Hours

Analysis

Maintenance Cost Notes
Yearly Pre-charge Verification $1833.00/year/aircraft This function is performed 26 times yearly per aircraft
Accumulator Failures $2413.00/month for overhauled unit
$367.00 /month for repaired unit
Fleet wide failures
2 Man-hours to Remove and replace one Failed accumulator and functional test system $94.00 each occurrence  

Maintenance
Yearly maintenance cost per Accumulator to support a fleet of 67 Aircraft:
$4340.00

Note: This does not include the cost of purchasing and maintaining inventory to support a fleet. In this case a typical MD-80 accumulator purchased new would cost $ 3680.00
Add to this the cost of capital and carrying cost of the inventory for each accumulator approximately 10% and the total per accumulator cost would be $4048.00.
Also not included in the above calculation are costs associated with flight delays and cancellations.
