Pressurization test after abnormal operation or repair
Special or check flights (non-revenue flights)
Load Report 15 – If hard landing occurs only on MLG
If LR15 trigger codes 7XXX – Normal Landing, No Action Required – GO
If LR15 trigger codes 4XXX – Hard Landing / Hard Overweight Landing – NOGO
Check Nz & Ny kpi values
Nz kpi: Vertical acceleration, aircraft gross weight, and roll angle.
Ny kpi: Lateral acceleration and bounce landing.
Nz kpi / Ny kpi indicator – Aircraft having enhanced DMU/FDIMU.
FDIMU (Computer) = DMU part + FDIU part
Hard landing on MLG – Assessment is based on Nz kpi and Ny kpi.
Green Zone – Normal
Trigger codes – 7XXX
Amber Zone – Hard / Hard overweight
Nz => 1.8 ; Ny => 0.45
Trigger codes – 4520 or 4620. (Hard)
Trigger codes – 4420 or 4320. (Hard overweight)
Red Zone – Severe hard / Severe hard-overweight
Nz => 2.06 ; Ny => 0.5
Trigger codes – 4510 or 4610. (Severe hard)
Trigger codes – 4410 or 4310. (Severe hard-overweight)
Inspection + Send raw data from DFDR or QAR to Airbus and obey airbus instructions.
When there are several valid trigger conditions, the minor triggered code has priority and is the only one printed on the report.
Hard landing on NLG – A hard landing on NLG is a landing where flight crew report gives the information about:
A touchdown on the NLG or
A hard touchdown on the MLG and NLG at the same time or
A landing with high pitch-rate de-rotation.
>> Inspection + Send raw data from DFDR or QAR to Airbus and obey airbus instructions.
You must not use the load report <15> to confirm a hard landing on NLG.
Load-Report – Make sure that the applicable load-report print-out is available.
If not, check if the related report is available in the DMU/FDIMU memory and do a printout of Stored Reports.
MCDU > AIDS > STORED REPORTS
Trigger code 1000 is a manual report request. It can not be used for a confirmation of a hard/overweight landing or excessive turbulence.
Trigger codes 2000 and 3XXX are not used in report 15.
Trigger codes 5XXX – used for excessive turbulence.
If you are not sure that the load report values are correct – Download the DFDR data and do a DFDR data analysis to make sure that the values are correct.
or Download DMU data to a PCMCIA-CARD. FDIMU is able to record AIDS data on an external Digital AIDS Recorder (DAR) and on an FDIMU integrated Smart AIDS Recorder (SAR) or on the PCMCIA card.
If the pilots reported a hard landing event but you cannot find the category of the landing because the load report <15> is not available: – Contact Airbus and Send the raw data of the event from the DFDR or the QAR to Airbus.
if the QAR or DFDR data cannot be downloaded immediately – You must do the inspection after a severe hard landing or a severe hard-overweight landing (Red zone). >> If you do not find damage during this inspection, the aircraft can temporarily return to service. >> In the shortest possible period and in less than 200 Flight cycles or 30 days.
Use Gloves – Health Risk
Use a plastic bag – to collect bird remains
Before start – get information from crew about the flight conditions:
Smell in the air conditioning outlets,
Navigation and radio system behavior,
Aircraft configuration (position of the landing gears and the flight controls),
Flight phase at the time when the impact occurred.
Do the inspection in three steps –
First step is a walk-around visual inspection of all aircraft surfaces. This is to find signs of bird strike and/or damage (identification of impacted areas). Do the walk-around visual inspection from –
