FAA issues flight restrictions over Venezuela

FAA issues flight restrictions over Venezuela

The U.S. Federal Aviation Administration has issued flight restrictions for U.S. aircraft in Venezuelan airspace due to ‘increasing political instability’.

The FAA prohibits flights below FL260.

Upset incidents lead EASA to issue emergency AD on CitationJets with active winglets

Upset incidents lead EASA to issue emergency AD on CitationJets with active winglets

The European Union Aviation Safety Agency (EASA) issued an emergency airworthiness directive (2019-0086-E) in the wake of recent in-flight upset incidents involving Cessna CitationJets, modified to have Tamarack ATLAS winglets.

The active load alleviation system (ATLAS), when operational, deflects the Tamarack active control surfaces (TACS) on the outboard wings. This system can aerodynamically “turn off” the winglet in specific conditions, thus dumping additional loads. Load alleviation enables a substantial increase in aspect ratio without the need for wing reinforcement and added weight, according to Tamarack. The modification is available for Cessna CitationJet models.

Recently, occurrences have been reported in which ATLAS appears to have malfunctioned, causing upset events where, in some cases, the pilots had difficulty to recover the aircraft to safe flight. Investigation continues to determine the cause(s) for the reported events. This condition, if not corrected, could lead to loss of control of the aircraft, EASA states.

The AD issued by EASA requires the Tamarack ATLAS to be deactivated and the TACS to be fixed in place. It also requires implementation of operational limitations and repetitive pre-flight inspections by amending the applicable flight manual.

Within 100 flight hours, owners must contact the ATLAS-manufacturer for modification instructions.

FAA demands replacement of AOA sensors on Cirrus SF50 jets following incidents

FAA demands replacement of AOA sensors on Cirrus SF50 jets following incidents

On April 18 the FAA published an emergency airworthiness directive (2019-08-51), requiring replacement of the angle of attack (AOA) sensor with an improved model.

This AD was prompted by Cirrus reporting three incidents of the stall warning and protection system (SWPS) or Electronic Stability & Protection (ESP) System engaging when not appropriate.
The SWPS and ESP may engage even when sufficient airspeed and proper angle of attack (AOA) exists for normal flight. SWPS includes the stall warning alarm, stick shaker and stick pusher. ESP includes under speed protection (USP). The SWPS and ESP engaging could potentially result in a STALL WARNING crew alert (CAS) message activation, accompanied by an audio alarm and stick shaker activation, followed possibly by either low speed ESP/USP engaging and/or the stick pusher engaging. The pilot will also observe the dynamic and color-coded (Red) airspeed awareness ranges displaying the stall band, regardless of actual indicated airspeed. These conditions, if not addressed, could result in the flight crew having difficulty controlling the airplane, lead to excessive nose-down attitude, significant altitude loss, and possible impact with terrain.

Cirrus and Aerosonic (manufacturer of the technical standard order AOA sensor) have identified the probable root cause as an AOA sensor malfunction due to a quality escape in the assembly of the AOA sensor at Aerosonic. Two set screws that secure the potentiometer shaft to the AOA vane shaft may have improper torqueing and no application of thread locker (Loctite) to secure the two set screws.

Before further flight, AOA sensor must be replaced before further flight.  Operators may fly the airplane to a location where the modification/corrective action can be incorporated using a special flight permit.

FAA publishes draft report on Boeing 737 MAX MCAS changes

FAA publishes draft report on Boeing 737 MAX MCAS changes

The U.S. Federal Aviation Administration (FAA) published a draft report from the Boeing 737 MAX Flight Standardization Board, after reviewing changes made by Boeing to the aircraft’s Maneuvering Characteristics Augmentation System (MCAS). Design issues of the MCAS were noted in the wake of two fatal Boeing 737 MAX 8 accidents.

The Flight Standardization Board reviewed only the training aspects related to software enhancements to the aircraft, stating the “system was found to be operationally suitable”.

The report is open to public comment for 14 days. After that, the FAA will review those comments before making a final assessment. Boeing Co. is still expected in the coming weeks to submit the final software package for certification.
