There have been 131 737 hull-losses, including 4 hijackings/bombings and 7 ground accidents. This may sound high but remember that over 5500 737’s have been built since 1967. This gives a 2.5% accident rate or approx 3 per year or one every 2.5 million flight hours. Furthermore, over 40% of occupants survive fatal 737 accidents.
The table below shows that more accidents have befallen the older aircraft. This is to be expected because they have amassed more flying hours / cycles and later generations have 38 years of design and technology improvements built in to them. A fairer comparison across the generations would be rate per flying hours or cycles but I do not have the data for this.
|Series||W/O’s||No Built||W/O Rate / A/C|
|737-1/200||102||1144||1 in 12|
|737-3/4/500||28||1990||1 in 76|
|737-NG||3||2500+||1 in 833+|
Details have been compiled from a variety of sources ie Aviation journals, books, news reports, internet sites (particularly the Aviation Safety Network) and of course the official accident reports, some of which is contradictory. Any additional information about any of these incidents would be gratefully received.
