Airworthiness Concern Sheet: FreeFlight systems FDL-978-XVR

Reason for Airworthiness Concern:

Latent failure of FreeFlight Systems ADS-B unit, model number FDL-978-XVR, to display air traffic or transmit location to other aircraft with active ADS-B In.

Federal Aviation Administration (FAA) Description of Airworthiness Concern:

Request for Information (For example: Proposed alternate inspection or repair procedures, cost impact, etc. Your comments or replies to the FAA need to be as specific as possible. Please provide specific examples to illustrate your comments or concerns.)

We have received reports of latent failures of FreeFlight model FDL-978-XVR ADS-B units. Troubleshooting determined that some units failed completely, while other units failed intermittently. Attempts to update the software and change any unit settings failed, as most parameters were “greyed out” and unable to be changed. Additionally, the failed units gave no indication of failure to the pilot.

Airworthiness Concern Sheet-Piper PA-32 Hoses Notice Number: NOTC9659

Airworthiness Concern Sheet-Piper PA-32 Hoses
Notice Number: NOTC9659

 

On February 19, 2019, an IA contacted the FAA in regards to the applicable aircraft under AD 2017-14-04. During an inspection, he had noticed that the PA28RT-201 Arrow IV was not listed on the AD, even though it has an identical oil cooler installation as the other PA-28 Arrows with the same engine installation. Since the FAA cannot hold Part 91 owners/operators to the service life limit requirements provided by the manufacturer in the maintenance manual, the AD would need to be updated with any additional models to provide the proper coverage to avoid the unsafe condition with the Type C hoses. In addition, since AD 2017-14-04 only addresses the oil cooler hoses, the FAA is also interested in whether the flying public is still utilizing Type C hoses in their engine compartments to see whether adding any other hose applications (i.e. fuel, turbocharger, etc) to the AD would be necessary to ensure safety is being maintained.

Airworthiness Concern Sheet-Piper PA-28 Fuel Selectors Notice Number: NOTC9658

Airworthiness Concern Sheet-Piper PA-28 Fuel Selectors 

Notice Number: NOTC9658

On July 11, 2019, Piper sent the FAA a Preliminary Risk Assessment regarding the first generation of fuel selectors installed on the PA-28 (first introduced in 1961) and recommended the FAA issued an AD to remove and replace the fuel selectors. The first generation of fuel selector mechanism installed on PA-28 models was a flat, round plate with a lever that could be manually rotated to one of four positions (each with its own detent): OFF – L – R – OFF. The design does not include any protection against inadvertent disruption of the position of the lever from its intended position nor does it prevent over-rotation which could result in mistakenly selecting the OFF position when not intended. After 1971, Piper released two different design improvement iterations (second generation and third generation) of the fuel selector to minimize the possibility of selector lever positioning errors.

SPECIAL AIRWORTHINESS INFORMATION BULLETIN
SUBJ: Equipment/Furnishings: Emergency Locator Beacon, G-Switch Failures
SAIB: CE-19-12
Date: June 18, 2019
This is information only. Recommendations aren’t mandatory.

Introduction

This Special Airworthiness Information Bulletin (SAIB) alerts you, aircraft owners and operators with installations of ACR Electronics, Inc. (ACR)(formerly Artex Aircraft Supplies, Inc. and Chelton Avionics, Inc. and doing business as Wulfsberg Electronics) emergency locator transmitters (ELT) G406-4, C406-1, C406-1HM, C406-2, C406-2HM, C406-N and C406-NHM identified by Part Number (P/N) and serial number (s/n) in Table 1 of this SAIB, of an airworthiness concern, specifically the ELT not transmitting alert and location signals in case of an accident due to an inoperative or a deteriorated G-switch. ELTs located in high vibration environments, for example in the tail of a helicopter, could have its acceleration sensor deteriorate after having been subjected to high levels of shock and vibration for five (5) years or more. This SAIB recommends best practices for the inspection, modification and replacement of these ELTs located in high vibration environments.

ELT Model P/N s/n (up to, inclusive)

G406-4 453-5012 210-08575
C406-1 453-5002 210-09438

SAIB: HQ-18-08R2: Engine Fuel and Control – Operation with Contaminated Jet Fuel

Date: June 10, 2019

This Revised Special Airworthiness Information Bulletin (SAIB) clarifies the recommendation regarding the dispositioning of jet fuel contaminated with Diesel Exhaust Fluid (DEF). The SAIB advises airplane operators, fixed base operators (FBOs), FAA repair stations, Flight Standard District Offices (FSDOs), and foreign civil aviation authorities of certain airplanes that uplifted jet fuel contaminated with DEF, or uplifted jet fuel using refueling equipment that was exposed to DEF. This SAIB also requests feedback regarding any service difficulties or operational anomalies of the identified airplanes and recommends that the owners of those airplanes consult with the original equipment manufacturers (OEMs) of their airplane, engine, and auxiliary power unit (APU) to determine the appropriate inspection and corrective maintenance actions on their airplane. This revision corrects and clarifies the Recommendations paragraph.

NPRM affecting Cherokee main wing spar

From the FAA:

Docket No. FAA–2017–1059; Product Identifier 2017–CE–035–AD

SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA–28–140, PA–28–150, PA–28–160, PA–28–180, PA–28–235, PA–32–260, and PA–32–300 airplanes. This proposed AD was prompted by reports of corrosion found in an area of the main wing spar not easily accessible for inspection. This proposed AD would require installing an inspection access panel in the lower wing skin near the left and the right main wing spars if not already there, inspecting the left and the right main wing spars for corrosion, and taking all necessary corrective actions. We are proposing this AD to address the unsafe condition on these products.

AD 2017-10-20

FAA SUMMARY: We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-31, PA-31-300, PA-31-325, and PA-31-350 airplanes. This AD was prompted by fatigue cracking in the fuselage station (FS) 332.00 bulkhead common to the horizontal stabilizer front spar attachment. This AD requires repetitive inspections to detect cracks in the bulkhead and any necessary repairs. This AD also provides an optional modification if no cracks are found that will greatly reduce the likelihood of the specified cracks. We are issuing this AD to correct the unsafe condition on these products.
