BriefingWire.com, 3/01/2021 - Airworthiness Directives
Airworthiness Directives (ADs) are legally enforceable rules issued by the Regulatory Authority of the Type Certificate Holder, (TCH) Supplemental Type Certificate Holder (STCH), or Original Equipment Manufacturer (OEM) (may also be issued by other Regulatory Authorities).
Now Consider the Following Statements :
· Airworthiness Directives (AD,s) are Mandatory.
· If an Aircraft is not in compliance with AD requirements its Certificate of Airworthiness is not valid and the aircraft shall not fly legally.
· AD,s are only issued by Regulatory Authorities â most usually the authority of the State of Design of the Aircraft or Product.
Preliminary Reports
Pilot of Crashed Citation Lacked Type Rating
Cessna 560 Citation V, Jan. 9, 2021, 14 miles southeast of Pine Grove, Oregon – The pilot of the Cessna Citation that crashed into the Mutton Mountains on the Warm Springs Indian Reservation did not hold a type rating for the accident airplane, though he was rated for the Learjet and the Grumman G-111 Albatross. Historical flight data and statements from acquaintances suggest that the accident took place on his first solo flight in the Citation. He was killed after the airplane spiraled down in a one-mile radius right turn from FL310 to the accident site at an elevation of 3,600 feet, a descent that took some eight minutes. The owner of a training facility in Arizona told investigators that while the private pilot had taken a Cessna 560 transition course in late 2020, he “had not performed to a level sufficient to be issued a type rating or single-pilot exemption.”
A Remarkable Success
Despite the initial difficulties, with the problems found in the batteries, the Boeing 787 has enjoyed considerable success around the world. It has racked up more than 1,500 orders, with the 1,000th delivered to Singapore Airlines recently.
Made of 85% carbon fiber, the aircraft features new technologies, such as electronic engine starting, electrical and non-hydraulic systems to reduce the weight of the aircraft. It also features, for the first time, a fully digitized cabin called the ‘glass cockpit’.

FAA Inspections
Despite the success, and despite the problems solved at the beginning, the 787 still has defects to the fuselage to this day. FAA issued an Airworthiness Directive (AD) for 222 787, given the decompression of the jet in the bilge barriers.
Via an Airworthiness Directive (AD) the US Federal Aviation Administration (FAA) has warned all Boeing 737 NG and MAX operators of a possible rapid decompression risk.
