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.

This Special Airworthiness Information Bulletin is to alert owners, operators, and maintenance technicians of an issue that could affect crew visibility when utilizing full face masks/smoke goggles manufactured by Collins Aerospace (formerly Rockwell Collins, B/E Aerospace). 

At this time, the airworthiness concern is not an unsafe condition that would warrant any additional airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39. 

We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (Zodiac) oxygen mask regulators. This AD was prompted by reports that certain silicon harness inflation hoses installed on certain flight crew quick donning mask harnesses have shown an unusually high premature rupture rate. This AD requires inspection and replacement of certain oxygen mask regulator harness inflation hoses. We are issuing this AD to address the unsafe condition on these products. 

This Special Airworthiness Information Bulletin is to alert owners, operators, and maintenance technicians of Textron Aviation Inc. (Textron) Model 172R, 172S, 182S, 182T, T182T, 206H, T206H airplanes, of failure of the “Sensor-Oil Pressure (Hobbs Switch)”, part number (P/N) 83278 as it is referred to in the illustrated parts catalogue. These engine oil pressure switches could have been provided new with the airplane or as a spares replacement part.

We are adopting a new airworthiness directive (AD) for certain Aspen Avionics, Inc. (Aspen), Evolution Flight Display (EFD) EFD1000 Primary Flight Display (PFD), EFD1000 Multi- Function Display (MFD), EFD1000 Emergency Backup Display (EBD), and EFD500 MFD units installed on various aircraft. This AD requires disabling the Automatic Dependent Surveillance- Broadcast (ADS-B) In function and revising the Airplane Flight Manual Supplement (AFMS). This AD was prompted by reports of flight displays repetitively resetting. We are issuing this AD to address the unsafe condition on these products.

Potential decreased service life of Slick 4-cylinder magneto distributor gear assemblies. Based on process and component improvements following the initial release of this service bulletin, the serial number range is being extended in this revision. Magnetos previously returned for compliance to SB1-15 must be returned or inspected for compliance to this revision SB1-15A.

This Special Airworthiness Information Bulletin is to alert owners, operators, and maintenance technicians of Textron Aviation Inc. (Textron) Model 208B airplanes of failure of the oil system “Valve – Flap Check” on serial numbers 208B2197 and 208B5000 and on. These airplanes are commonly referred to as “208B EX” or “EX” and incorporate the Textron PT6A-140 engine installation.

This Special Airworthiness Information Bulletin (SAIB) advises airplane operators, fixed base operators (FBOs), FAA repair stations, Flight Standards District Offices (FSDOs), and foreign civil aviation authorities of jet fuel supplies for which the concentration of aromatic hydrocarbons and the net heat of combustion may not have been measured in accordance with methods specified by the type certificate (TC) holder. These jet fuel supplies would not be compliant with the FAA approved jet fuel operating limitations and should not be used on the TC holders’ products.

A recent accident involving an in-flight propeller failure and separation has again brought to light the need for continued diligence in the use of liquid penetrant inspection methods.

This Special Airworthiness Information Bulletin (SAIB) advises airplane operators, fixed base operators (FBOs), FAA repair stations, Flight Standards District Offices (FSDOs), and foreign civil aviation authorities of certain airplanes that uplifted jet fuel contaminated with diesel exhaust fluid (DEF), or uplifted jet fuel using refueling equipment that was exposed to DEF.

This revised Special Airworthiness Information Bulletin (SAIB) informs owners, operators, repair stations, and flight standard district offices that compliance with a new or revised airworthiness limitation section (ALS) issued by a design approval holder (DAH), or other entity, as a type design change is not mandatory for in-service aircraft operating pursuant to Title 14 of the Code of Federal Regulations (14 CFR) part 91, unless the aircraft owner/operator voluntarily incorporates the change, it is mandated by an airworthiness directive (AD) to resolve an unsafe condition or required by a previously agreed upon maintenance program..

This Special Airworthiness Information Bulletin (SAIB) alerts registered owners, operators, and certified repair facilities of all airplanes equipped with Teledyne Continental Motors (TCM) Model C75, C85, C90, C125, C145, O-200, O-300, and GO-300 series and Rolls-Royce plc (RR) C90, O-200 and O-300 series reciprocating engines of miscommunication regarding the applicability section of AD 94-05-05 R1, effective on February 13, 1996. The FAA has received reports that FAA personnel have provided guidance that has resulted in confusion on complying with AD 94-05-05R1. The intent of this SAIB is to correct this miscommunication.

A recent accident involving an in-flight propeller failure and separation has again brought to light the need for continued diligence in the use of liquid penetrant inspection methods.
