The document discusses the causes of plane crashes and aims to prevent them. It analyzes factors that influence crash risk like the plane type, size, pilot, and weather. It identifies three main departments that are often responsible - management, systems, and mechanical. Specifically, it examines a 1985 Japan Airlines crash caused by improper repairs to the plane's bulkhead. It recommends improved maintenance training and reporting mechanisms to enhance safety.

3. • OBJECTIVE : TO EXPOSE POTENTIAL CAUSE
OF PLANE CRASH.
• AIM : TO PREVENT PLANE CRASH.

8. • The odds of a plane crash depend on a various amount
factors, such as:
The type of plane
The size of the plane
The pilot
The time of year
The weather
• BUT actually, the plane crash is also because of the
main department which are :
o Management Department
o System Department
o Mechanical Department

10. • lack of motivation
• fatigue and stress
• time pressure
• misperception of hazards
• inadequate skills

11. • Date: August 12, 1985
• Time: 18:56
• Location: Mt. Osutaka, near Ueno Village, Japan
• Operator: Japan Air Lines
• Flight #: 123
• Route: Tokyo - Osaka
• AC Type: Boeing B-747-SR46
• Registration: JA8119
• cn / ln: 20783/230
• Aboard: 524 (passengers:509 crew:15)
• Fatalities: 520 (passengers:505 crew:15)
• Ground Fatalities: 0

12. • The aircraft suffered an aft pressure bulkhead
failure at 23,900 ft. The aircraft had severe
control difficulties with loss of all controls and
eventually after 40 minutes, collided with a
mountain. Improper repair of the bulkhead
while being supervised by Boeing engineers
after a tail strike in 1978 is the reason for this
crash. Worst single plane disaster in aviation
history. Kyu Sakamoto, 43, famous for his
Japanese song "Sukiyaki" was killed in the
accident.

13. • Improper repairs by Boeing after a tail strike 7
years earlier, led to a rupture of the pressure
bulkhead and loss of all controls.

14. • Continuous maintenance re-training for
aircraft technicians.
• Create mechanisms for reporting, investigate
reports, and provide legal protections to the
people who informed them
• Human factors training for airline
management and aircraft engineers

15. BACK

17. - poor communication between the airport
operator and air traffic controllers
- Mistakes by controllers that working at radar
facilities
- Security control
- low security awareness

18. BACK
• Mentally go over exactly what you will say
before touching the radio and keep it in mind.
• Determine your position
• Acquire necessary information
• Communicate your request in a professional
and organized manner.
• Tighten up the security

20. • System Department is where Avionic’s
engineer work. They will check the
system, the engine, radar and the
electrical in the aircraft.
• When system in aircraft fail, the plane
must be in serious problem. That can
cause the plane accident.

21. • Follow all the safety rules and
regulations, the checking procedure.
• Obey all the standing order procedure
• Never try to shortcut
• Don’t ever compromise.
