Every investigator should use his / her own experience while investigating and he / she should employ this experience in analyzing the collected data. All analysis is to be put on reports and the AAIU IIC is responsible to point out the probable cause/s. The following are references and guidelines for the investigators that may be followed depending on the investigation:

 

Every investigator should use his / her own experience while investigating and he / she should employ this experience in analyzing the collected data. All analysis is to be put on reports and the AAIU IIC is responsible to point out the probable cause/s. The following are references and guidelines for the investigators that may be followed depending on the investigation:

  1. For Aircraft Power plant, Airframe, Structure and Avionics Investigation:
    1. The investigator should always refer to the relevant manuals (Aircraft Maintenance Manual, Engine Maintenance Manual, Engine Overhaul Manual, Troubleshooting Manual, Aircraft Wiring Manual, Component Maintenance Manual, Maintenance Planning Data Manual, Aircraft Loading / Unloading Manual, Aircraft Weight and Balance Manual, Structure Repair Manual...etc.).
    2. All the collected parts and components are to be inspected thoroughly by using the feasible equipment and techniques in order to evaluate the damage or malfunction, the type and cause of damage is to be identified depending on the inspection.

Many technical manuals and publications (ICAO, FAA... etc.) are to be consulted for determining the nature of failure and the cause.

The mechanical part may be inspected by any suitable means and equipment in order to identify the type of damage; if under a normal stress, shear stress, twist, fatigue, thermal fatigue or intergranual defects due to poor chemical composition or manufacturing defects.

The investigator/s should be familiar with the testing techniques; he/they may use Non Destructive Test; X-Ray, Ultrasonic, Eddy Current, Borescope or Florescent Penetrant.

If any consultation is required from any specialist, AAIU IIC should request from Director AAIU to contact that specialist. The following are recommended specialists in the field of Metallurgy science:

  • Scientific Association.
  • Jordanian Governmental and Private Universities.
  • Royal Jordanian Air Force.
  • Royal Jordanian Army.

The investigator may use the Operators’ laboratories and equipment. In case of component investigation, any of the Operator’s test benches may be used, if not feasible due to any reason, the investigator may use or may send the involved component for testing to any specialist facilities inside or outside the Kingdome.

    1. The data extracted from the aircraft Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR) is to be analyzed in order to find the aircraft systems performance prior to the accident. FDR and CVR specialists should accurately supply the investigator with all the readings.
  2. Aircraft Operations Investigation:
    1.  The investigator should refer to all relevant manuals (Aircraft Flight Manual, Aircraft Operations Manual, Jeppesen Charts... etc.). The Investigator may depend on his / her experience and should consult any specialized hand books or publications (ICAO, FAA…etc.) for analyzing the data.
    2.  All collected data should enable the investigator to establish the aircraft flight path prior to the accident. The operations investigator should strongly depend on the wreckage plots, measurements and any photographs taken in the accident scene.
    3. FDR and CVR specialist should supply the investigator with all requested readings.
  3. Meteorology Investigation:

The Meteorology expert should be able to analyze the data in order to evaluate the weather condition. He may consult any of the specialized hand books or publication.

  1. AIR Traffic Control Investigation

The ATC expert should be able to analyze all the data in order to assist the Operations Investigator in finding the aircraft flight path prior to the accident. He / She should be able to analyze the CVR and the radar voice recorder. He / She should always refer to the relevant manuals and he / she may refer to any of the specialized hand books or publication.

  1. FDR and CYR Investigation:

The specialist of aircraft FDR should have the ability to read any of the FDR readings and plots and compile them, similarly, the CVR specialist should have the ability to hear and compile any voice in the CVR and write a full transcript. They should, upon request, sit with the investigators and explain any relevant information.

  1. Other Investigations:

The other investigations (Human Factors, Witness Statement, Evacuation, Search and Rescue, and Fire fighting…etc.) are to be conducted by AAIU Investigators who should be trained for such investigations; any consultations may be taken from the specialist persons or organizations.

All the above investigation and analyses are to be put in reports by every nominated investigator and submitted to AAIU IIC who will study and evaluate them and request fix corrections or more investigations if required. Pointing out the probable cause/s is the responsibility of AAIU IIC.
