Technical Planning - Flynas
Overview
Check Types
Pre-flight check
is valid for 4 sectors and maximum up to 6 sectors in case of flight diversion.
requires a technical log book entry
Daily check
requires a technical log book entry and RTS
contains the requirements of the regular MIP task with 24 HR elapsed, 3 days intervals and FLYNAS initiated task at a maximum of 48 hours (UTC) since last daily check
Weekly check
contains the requirements of the MIP systems and zonal task with 8 days intervals
"A" Check
This contains the requirement of MIP task with 750 FH, 750 FC and 4 MO intervals and its multiples
"C" Check
This contains the requirement of MIP tasks with 7500 FH, 5000 FC and 24 months intervals and its multiples.
"6Y" Check
This contains the requirements of MIP tasks with intervals 6 years and 72 months.
"12Y" Check
This contains the requirements of MIP tasks with intervals 12 years and 144 months
Out of phase items
Out of Phase Task are those tasks whose interval program are not aligned to the defined scheduled maintenance checks. These items will be monitored, scheduled, and accomplished on an individual basis.
RVSM flight monitoring requirements
HMU requirements compliance
A minimum of 60% of the fleet is required
Item classification and extension
Items controlled by FH
More than 5000 flight hours (500 flight hours)
5000 flight hours or less (10%)
Items controlled by Flight Cycle (Landing)
500 landings or less (5% or 25 Landings)
More than 500 landings (5% or 250 landings)
Items controlled by calendar days
More than 3 years (3 months)
More than 1 year (2 months)
1 Year or less (10% or 1 month)
Duties
Updating last done / next due sheet by reviewing hard limit component (HTC)
Short term maintenance plan (3 months)
To maintain and monitor the daily routine maintenance plan including Ad's, SB's, checks, component removal/replacing
Long term maintenance plan (1 year or 2 year ) Major check
MIP tracking daily in TRAX and Excel
Issue/produce/update the required work order for schedule maintenance plans
MIP
ZONAL MAINTENANCE PROGRAM
objective
This section provides the General Visual Inspection (GVI) requirements for each aircraft zone to check system and power
plant installations and structure for security and general condition.
SPECIAL INSPECTIONS
Special Inspections listed in this inspection program are additional tasks required to ensure the continued airworthiness
of the aircraft. These inspections are therefore supplemental to the basic core inspection tasks in this program manual.
Structures maintenance program
Levels
General Visual Inspection (GVI)
Detailed Inspection (DET)
Special Detailed Inspection (SDI)
Inspection philosophy
Metallic
Fatigue Damage (FD)
is primarily dependent on the ground-air-ground loading variation, which occurs once per flight. Therefore, flight cycles (FC) are used as the unit for it. For some fatigue related to SSI in addition to FH.
Environmental Deterioration (ED)
(e.g. corrosion, stress corrosion) is mainly time dependent, inspection intervals and thresholds are based on calendar time (Years).
Accidental Damage (AD)
AD is considered as ED or the FD task, or both, according to the AD consequences. AD is therefore subject to maintenance
requirements expressed in FC (and FH) or calendar time or both
Non-metallic
Ageing Deterioration
Inspection intervals and thresholds are based on calendar time.
Accidental Damage
Deterioration caused by accidental damage is subject to inspection intervals based on calendar time.
ALS part 2
Objective
to maintain the continuous airworthiness of the aircraft structure and to control corrosion to level 1 or better
CORROSION PREVENTION CONTROL PROGRAM (CPCP)
Level 2 Corrosion
Level 3 Corrosion
Level 1 Corrosion
Sampling program
The purpose of the Sampling Program is to detect systematic deterioration caused by the environment and/or fatigue, on a
group of aircraft selected from those which have the highest age within a considered fleet.
The sample size is 1 or 5 or 20% of the total fleet per
aircraft type. (for the oldest aircraft in years)
Systems, APU, and Power plant maintenance program
Failure Effect Categories (FEC) depending on the consequence of failure
FEC 8 : Hidden Function Safety Effects
FEC 9 : Hidden Function Non-Safety Effects
FEC 7 : Evident Economic Effects
FEC 6 : Evident Operational Effects
FEC 5 : Evident Safety Effects
Tasks resulting from systems safety assessment are identified as Certification Maintenance Requirements (CMR)
(CMR*) task interval cannot be escalated
(CMR**) task interval can be escalated
ALS part 4 and 5
Maintenance plans
Short term maintenance (next three months forecasting)
Work flow
Uploading the work orders on the workload sheet (every morning)
The line maintenance team will receive the WOs from the PCC to perform them
PCC will receive the completed tasks and update the actual flight cycles
Send the workload sheet to the PCC
Browsing the E/Cs and their A/Cs from TRAX (Due dates)
Creating the short term maintenance plan every month (work orders)
Creating the required pick lists every 10 day in advanced and attach it to the workload sheet
By the end of the month, a new plan for the third month will be add to the short term plan so the total remain 3 months
Work orders categories
IMP
Engineering order (AD, SB)
Component replacement
Deferred defect (MEL/CDL)
Work order inputs
Man power
Tools/Materials
Ground time
Pick list
Heavy check
C check package
Redelivery
Updating in every 3 months
C of A preparation
2- preparing AD, SB, and HTC
3- making sure there is no overdue for AD, SB, or HTC
4- making sure that AD, SB, and HTC are good for a year in future
1- receiving c of a request from QA
5- send the required documents to the records
