Antonov AN-2 Aircraft

Antonov AN-2 AircraftThe Antonov AN-2 is a Soviet manufactured single engine bi-plane which has been in production since 1946.

It is used as a light utility transport for missions requiring a slow flying biplane such as parachute jumping, aerial application and use on short, non-improved airstrips.

It carries a crew of 1-2 and 12 passengers and has a maximum takeoff weight of 12,000 pounds. It is powered by a 9 cylinder supercharged radial engine rated at 1,000 hp.

Maximum cruise speed is 120 mph and a range of 525 miles.

This is the aircraft that took off just 39 seconds before the DR400 departed, and the wake turbulence it generated was found to be the cause of this tragic accident.

Lesson?

Never assume! Even an aircraft of this size can generate enough wake turbulence to cause aircraft upset if to close behind! Always allow at least 2 minutes before departing behind one of theses.

What do you think?

Until next time keep your wings straight and level Hersch!
