“The Michigan men’s basketball team plane was involved in an accident Wednesday afternoon. After attempting to take off in high winds, takeoff was aborted and, after strong braking, the plane slide off runway. The plane sustained extensive damage but everyone on board was safely evacuated and is safe. The team is making alternate travel plans.”

1. The Plane Was Travelling About 150 MPH When It Skidded Off the Runway

Initial news reports weren’t able to put the whole situation into perspective.

Michigan coach John Beilein said that reporting that it’s a plane “skidding off the runway” didn’t paint the right picture. Instead, the plane was traveling extremely fast as it attempted to get off of the runway, Beilein said.

It wasn’t just a plane skidding off a runway. It was full going, 150 miles an hour, we can’t stop. And our kids got — thank goodness the plane didn’t flip. All kinds of things could have happened once we got off the plane and looked.

He said that crews aboard the plan acted quickly to ensure safety, but it was a very scary situation. Thankfully, the plane didn’t strike any large objects or slide any further, otherwise the crash may have had fatal results.

2. The Plane Malfunctioned Because of an Equipment Issue

The National Transportation Safety Board issued an update to the incident March 22 and said that the cause seems to be an equipment malfunction.

The statement said that while probable cause and a conclusion hasn’t yet determined, preliminary information and details have been found.

The NTSB said that a post-accident examination found that the “right elevator” on the plane was jammed into a “trailing edge-down position.” Further inspection showed that the elevator on the plane was damaged and restricted movement.

When investigators tried to move the elevator surfaces by hand, the left elevator moved normally, but the right elevator was jammed in a trailing edge-down position (airplane nose down). Upon further inspection, the right elevator geared tab inboard pushrod linkage was found damaged which restricted movement of the right elevator surface but allowed movement of the control tab. After the damaged components were removed, the elevator could be moved by hand.

On airplanes, elevators help control the pitch on the aircraft and provide measurements to how far the nose of a plane is tilted up or down.

FAA AD Boeing Company Model 767-200 and -300 series airplanes

SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200 and -300 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the frame-to-floor-beam joints and frames common to shear ties at certain locations of fuselage structure are subject to widespread fatigue damage (WFD). This AD requires inspections for cracking of certain frame inner chords and webs common to the floor beam joint and at frames common to the shear ties at certain sections, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

Oil prices hit eleven-year low as global supply balloons

Brent crude oil prices hit their lowest in more than 11 years on Monday, while U.S. crude flirted with seven-year lows on more signs that swelling global supply looked set to outpace tepid demand again next year.

FAA AD 2015-21-08 (Boeing 737 upper wing skin) Eddy Current inspection

This AD requires repetitive eddy current inspections for any cracking in the inspar upper skin, and related investigative and corrective actions if necessary. This AD was prompted by a report that an operator discovered a crack in a certain section of the inspar upper skin, just forward of the rear spar on the right wing. We are issuing this AD to detect and correct any cracking in the inspar upper skin and rear spar upper chord, which could result in the inability of the structure to carry limit load, or result in a fuel leak, which could prevent continued safe flight and landing.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain serial number (S/N) GE Aviation Czech s.r.o. M601E-11, M601E-11A, and M601F turboprop engines with certain part number (P/N) gas generator turbine (GGT) blades, installed. This AD requires removing from service any affected engine with certain GGT blades installed. This AD was prompted by the determination that certain GGT blades are susceptible to blade failure. We are issuing this AD to prevent GGT blade failure, which could lead to engine failure and loss of the airplane.
