The right main landing gear collapsed on impact when a Delta flight rolled over upon landing at Toronto's Pearson International Airport last month, according to a preliminary report.

Now, the FAA says 737s and 757s may also be affected. It notes that workers at the same maintenance site used the same grinder on main landing gear cylinders of 166 Boeing 737s and of 20 757s.

UAVOS, a company in UAS engineering and manufacturing, announces the development of its latest Main Landing Gear Spring, designed to improve durability, performance, and safety for unmanned aircraft.
