787 Reliability Statistics 2

Introduction and Definitions

Purpose

The function of the monthly Reliability Statistics report is to provide data on the engineering operation of the fleet. It monitors

operational statistics, PIREPS, Technical Interruptions, unscheduled component removals and engine statistics. In the near future

other areas will be included. This report is for general circulation.

The reports are the routine communication channels for the Reliability Management Programme which exists to ensure safe and

reliable fleet operation with maximum economy of maintenance.

Definitions

Upper Control Limit A rate of occurrence which, if exceeded, triggers an investigation and corrective action.

Pireps - Mean + 2 times Standard Deviation of the 3 month Pirep rate

Delays – Number and severity by ATA system

Alert Occurs when the 1 month rate of occurrence exceeds the UCL.

ATA System Status

‘Alert’ - Exceedance of the upper control limit, no in-depth analysis required, will be monitored.

Key to Pirep and Delay ATA graphs

3-month rate

Upper Control Limit

Trend line

APU Hours The auxiliary power unit operating time from start up to shut down.

Thomson Airways record APU hrs. as landings 1.5

MTBUR Mean Time Between Unscheduled Removals

A performance figure calculated by dividing the total unit flying hours (airborne) accrued in a

period by the number of unscheduled unit removals that occurred during the same period.

Technical Delay Delays greater than 15 minutes caused by technical malfunction of aircraft

(or suspected technical malfunction). Includes delays out of scheduled maintenance caused by

technical malfunctions.

Despatch Reliability Percentage of flights that do not incur a technical delay.
