Introduction: Maintenance Management

• Boeing supplied its MPT to Jet Airways

• MPT is maintenance performance toolbox of software solutions

• MPT gives quick access to streamline the cumbersome process of

customizing online maintenance manual

• Jet Airways engineering and Maintenance facility includes C checks

upgraded further to D checks

• Carries its maintenance activities at night halting statins at Chennai,

Kolkata and Bangalore.

Technical Dispatch Reliability

• Having the highest reliability rate of 99.2 % and above

• Maintenance operation can be divided into 3 categories:

Line maintenance

C or phase 10 checks(C checks)

Heavy maintenance checks(D checks)

Line Maintenance

• Consists of

Routine, Scheduled maintenance checks

Preflight, daily and overnight checks

any diagnostic and routine repairs

C Checks

• Carried out after a maximum of 4800 flight hours

takes an average of 8 days for its Boeing Aircraft

• Sometimes results in a loss of service for a period of up to 10 days

• Leased a maintenance facility at Bangalore from HAL on its Boeing

Aircraft

Heavy Maintenance or D checks

• Consists of more complex inspections

• Servicing of Aircrafts that require longer maintenance period

• Follows a prescheduled agenda of major overhauls defined in the Aircraft

manual

• Based on number of flights flown by the Aircraft or the age of the Aircraft

• A typical D check may result in a loss of service of a Boeing 737 aircraft

for approx. 45 days

• Currently carried by the US FAA and the DGCA

Cost control Measures

• Cost of quality depends upon

Prevention

Appraisal

Internal Failure

External Failure

• TQM

• TPM

• Preventive Maintenance can be used

Areas of quality Management and Operational Strategy

• Operations Strategy

Planning, analyzing, implementation and control

Decisions that relate to the design of a process and infrastructure

needed to support it.

Quality, assurance and control approaches

Make great products and services & to deliver service quality

Make the product to Deliver products when serviced

Ability to deal with dynamic market demand

Long term competitive strategies with Corporate strategies

Raliability

Maintenance

• It has established a maintenance hanger complex with workshop

and allied facilities at Mumbai.

• The cost of the maintenance hanger and related workshops and

engineering facilities is US Dollar 15 Million.

• The hanger is used for C checks, line checks, storage, and minor

rectification of engines and workshops for composite structural

repairs.
