Abstract
This chapter outlines a number of failure investigations of tail rotor gearbox center housings from a medium-lift helicopter. These housings are manufactured from magnesium alloy sand castings which are susceptible to corrosion if surface-protective coatings become damaged; hence they sometimes fail to achieve their design life. However, approximately 15 years ago these housings also started to experience cases of fatigue cracking, leading to even higher scrap rates.
