Item 05-00-01 refers to

Non-Safety Related Equipment

2

Item 25-20-01 refers to

Passenger Convenience

3

All unserviceable equipment must be clearly labelled as ....

“INOP”

4

“Dispatch” or “Commencement of Flight” is ...

... the point at which the aircraft moves under its own power

5

Rectification Interval (RI)

Define Cat A

Time is specified in the appropriate MMEL item

o Where specified in days; excludes the day of discovery
o For a time period other than days; starts at time of deferral

6

Rectification Interval (RI)

Define Cat B

Cat B = 3 days (excluding day of discovery)

7

Rectification Interval (RI)

Define Cat C

Cat C = 10 days (excluding day of discovery)

8

Rectification Interval (RI)

Define Cat D

Cat D = 120 days (excluding day of discovery)

9

Main Maintenance Bases for the 777

LHR and LGW

10

Once an aircraft has dispatched from a Main Maintenance Base then the restrictions to dispatch from such a base.....

no longer apply

11

After dispatch from a Main Maintenance Base on the first flight of the day it becomes a

Transit Station for the rest of the day (GMT)

12

The ACF procedure can be used if (3 points):

 Defect complies with the MEL
 No maintenance is required (or affects non-safety related equipment)
 There are no spares/personnel readily available

13

ACF not to be used (2 points):

 From Main Maintenance Base when a restriction “No dispatch main maintenance base” exists
 For CDL items

14

SEA may be applied where:

 MEL Maintenance Procedure is required prior to dispatch, and,
 No BA Authorised Engineer is available

15

What is an Engineering Design Instruction (EDI)/ Engineering Design Approval (EDA)

EASA Part 21 Allows BA to approve deviations from the manufacturers approved documentation

Extra info:

 This authority is conveyed in the EDI/EDA
 EDI = The “How to Do It”
 EDA = Substantiation and Classification
 If it is not possible to grant an EDI/EDA then a Temporary Repair Mandate may be issued

Only to be used for items with RI of...

 Items with repair intervals of B or C ONLY (not A or D)

 When events beyond the operators control have precluded rectification

CAA to be provided with details within 10 days

17

Where a performance penalty is listed as negligible no more than XXX items may be missing without penalty

3 items

18

CDL Weight Reductions

For each missing item more than 3 “negligible” items reduce the take-off, landing and En-route climb limits by XX kgs

46kgs

19

CDL

En-route Diversion Speed Effects (DDG 3. CDL)

En-route climb penalties are based on the maximum lift/drag ratio speed. Correct the penalties by the listed factor for flight ...

at other speeds

20

CDL

En-route Fuel Mileage Effects

0.25% per 454kg penalty
