Uncommanded Smooth Pitch-Up During Flap Extension

Question 1

What is the indication for a flap slab interconnect failure when your flaps are originally up and then you attempt to extend them?

Answer 1

As you extend the flaps, a smooth but definite pitch up will occur. You will notice you require large amounts of forward stick forces to maintain level flight

Question 2

What failure could you confuse a flap-slab interconnect failure with when you are configuring flaps?

Answer 2

Trim failure. Proper analysis of configuration and control movements at the time of occurrence are essential

Question 3

What should you do with your pattern airspeeds if you are landing with less than 60% flaps?

Answer 3

Fly AOA and on-speed indications

Question 4

What are the correct (checklist) actions to take during a flap-slab interconnect failure during flight when extending the flaps.

Answer 4

1. Flaps - Reposition to up
2. Throttles - As required to maintain above no-flap flying airspeed
3. Land with no flaps

Generally, the corrective action is to un-do what you did to cause the issue, I.e. move the flaps back to up. Maintain a safe airspeed for flight and perform a no flap landing
