The FAA is adopting a new airworthiness directive (AD) for Diamond Aircraft Industries Models DA 40, DA 40 F, and DA 40 NG airplanes. The AD addresses an issue with fuel tank connection hose deterioration that could result in contamination of the fuel system and restriction of fuel flow. The AD, effective August 4, 2020, requires actions to address the unsafe condition of these products. See the AD for more details.
The notice of proposed rulemaking (NPRM) was prompted by a report of a wing separation caused by fatigue cracking in a visually inaccessible area of the lower main wing spar cap. This action revises the NPRM by adding and removing certain models of airplanes in the Applicability, proposing to require the use of service information that was issued since the NPRM, and clarifying some of the proposed actions.
Proposed AD Affects Roughly 6,600 Cessna Aircraft
A proposed airworthiness directive stands to affect 6,586 Cessna 180, 182, and 185 models, driven by a report of cracks found in the tailcone and horizontal stabilizer attachment on a 185 that had displayed excessive play while undergoing maintenance. “After a detailed inspection, the tailcone reinforcement braces were found cracked on both sides of the airplane,” according to the FAA’s proposed AD document.
Upon investigation of other related models from the same general age cohort, the FAA found similar cracking on 29 additional airplanes. “The FAA determined that the combination of the attachment structure design and high loads during landing contribute to the development of cracks in the tailcone and horizontal stabilizer attachment structure,” reported the proposed AD. “This condition, if unaddressed, could result in failure of the horizontal stabilizer to tailcone attachment and lead to tail separation with consequent loss of control of the airplane.” Guidance already exists in the most part for the remedy of the AD, as the FAA determined that Textron Aviation Single Engine Mandatory Service Letter SEL-55-01, dated December 7, 2017, calls for inspection and remediation of the same areas on the empennage of those Cessna models. The action’s comment period ends on June 29, 2020, so pilots are encouraged to weigh in soon if they have valuable information or opinions to share.

Following a request from EAA and AOPA, the FAA has released a policy that will make it easier for some owners of experimental aircraft to obtain special flight permits (SFPs) for their airplanes in order to reposition them for condition inspections.
Airworthiness Directives (ADs) are legally enforceable regulations issued by the FAA in accordance with 14 CFR part 39 to correct an unsafe condition in a product (an aircraft, engine, propeller, or appliance). Do you know how to find ADs applicable to your aircraft? Check out this Aviation Maintenance Safety Moment video to see how:
There are somewhere near 50 RV's owned by EAA288 members, many of them "A" models and maybe a few hundred or more varieties of other aircraft owned by our members. In the Van's world, there have been numerous discussions in the media and around airports about the RV "A" models and the nose wheel design. Recently on the Vans Air Force website there was a discussion regarding an RV-9A accident at an Australian airport. The official accident report can be found at the following link: https://www.atsb.gov.au/publications/investigation_reports/2017/aair/ao-2017-001/
A most interesting video taken from a camera mounted under the left wing of the accident aircraft adds a tremendous amount of information to be considered. While making no comments about the cause, I found the report and companion video an excellent learning experience causing one to think about landing, or recovering from a "bounce" and continuing to land the aircraft or going around. Something all pilots should consider while on final approach (or even in advance of that). This thought process should be applied to each individual's aircraft. After all, our aircraft are not all created equally (neither are the pilots). Think about what you would do!
Should you choose to watch the video, the settings icon (the geared wheel) on the lower right corner has options for the watching the video at different speeds. For instance, using the .25 video speed versus the normal speed, provides a different perspective of the accident. (Note: While both people on board survived, they were seriously injured.)

July 16, 2020 UPDATE: (SAIB) AIR-20-10 on May 29, 2020 for Cessna 210 airplanes.
The FAA issued Special Airworthiness Information Bulletin (SAIB) AIR-20-10 on May 29, 2020 for Cessna 210 airplanes affected by AD 2020-03-16. The SAIB advises owners and operators of four alternative methods of compliance (AMOCs) associated with AD 2020-03-16. One of the Global AMOCs available extends the compliance time for the AD to September 9, 2020 due to difficulty meeting the original 60 day compliance time due to factors associated with the COVID-19 virus. The SAIB also addresses some commonly asked questions associated with AD 2020-03-16. Please select SAIB to link to the SAIB posted in the FAA's Regulatory and Guidance Library.
The FAA has extended the compliance time due to the Covid-19 virus.
The FAA has issued a Global AMOC (Alternative Method of Compliance) for AD 2020-03-16 to extend the compliance time from 60 days to September 9, 2020. This extension changes the compliance time from 60 days to approximately 180 days. The original 20 hours time-in-service (TIS) compliance time identified in AD 2020-03-16 remains the same.
The FAA is adopting a new airworthiness directive (AD) for all Textron Aviation Inc. (Textron) (type certificate previously held by Cessna Aircraft Company) Models 210G, T210G, 210H, T210H, 210J, T210J, 210K, T210K, 210L, T210L, 210M, and T210M airplanes. This AD requires visual and eddy current inspections of the carry-thru spar lower cap, corrective action if necessary, application of a protective coating and corrosion inhibiting compound (CIC), and reporting the inspection results to the FAA. This AD was prompted by the in-flight break-up of a Model T210M airplane in Australia, due to fatigue cracking that initiated at a corrosion pit, and subsequent reports of other Model 210-series airplanes with widespread and severe corrosion.
