Defect Analysis on Boeing 737-400 Skin Panel Rivet Row Aft Ward Fuselage

Abstract

Non-destructive testing defect analysis has been long used as a lead to safeguard against an incident due to damage limitation. This is especially vital for the aging aircraft to protection against possible issue respectively. Defect analysis using non-destructive testing mean to be conducted on Boeing 737-400 skin panel rivet row aft ward fuselage. Project were conducted at University Kuala Lumpur Malaysian Institute of Aviation Technology (UNIKL MIAT). The purpose of this project is to determine percentage of material loss in between rivet row of Boeing 737-400 skin panel from BS 747 to BS 967, crack inspection on Boeing 737-400 skin panel rivet row aft ward fuselage and to analyses collected data for usability of rivet panel on Boeing from 737-400 BS 747 to BS 967. The result for the inspection carried out on the fuselage BS 747 to BS 967 shows that the subsurface has exceed 30% of material loss, crack has exceeded 0.2 inch and conductivity are not within limitation as per the Aerospace Material Specification AMS2658C. Such data for future references about its reference point data on the current state and condition of the aircraft were created and the aircraft require further investigation and possible repair need to be carried out to ensure safety for students and lecturer doing practical on the aircraft.
