SAIB: NE-14-13

This Special Airworthiness Information Bulletin (SAIB) alerts you, owners, operators, and certificated repair facilities of Lycoming Engines of the possible failure of engine thru-studs, and/or cylinder mounting studs. The airworthiness concern is not an unsafe condition that would warrant airworthiness directive action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.

AD 2014-05-29

We are superseding airworthiness directive (AD) 2009-16-03 for certain Continental Motors, Inc. (CMI) IO-520, TSIO-520, and IO-550 series reciprocating engines, with certain SAP replacement parts manufacturer approval (PMA) investment cast cylinder assemblies installed. AD 2009-16-03 required initial and repetitive inspections and compression tests to detect cracks in those cylinders. This new AD requires that additional engines be added to the applicability. This AD was prompted by the need to add to the applicability all other engine models approved for the use of CMI 520 and 550 cylinder assemblies, such as the CMI 470 series engines when modified by supplemental type certificate (STC), with affected SAP investment cast cylinder assemblies installed. We are issuing this AD to prevent the separation of the cylinder head, damage to the engine, and damage to the airplane.

SAIB: NE-14-15

This Special Airworthiness Information Bulletin alerts you, owners, operators, and certificated repair facilities of aircraft equipped with Hartzell Propeller, Inc. various propeller models that have certain serial numbers and part numbers (P/N) of the potential for corrosion of the guide rods. This corrosion could lead to inability to adjust the pitch of your propeller. A detailed list of effectivity can be found in Hartzell Propeller Alert Service Bulletin (ASB) HC-ASB-61-351. At this time the airworthiness concern is not an unsafe condition that would warrant airworthiness directive action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.

AD 2014-17-03

We are adopting a new airworthiness directive (AD) for certain Technify Motors GmbH (type certificate previously held by Thielert Aircraft Engines GmbH) TAE 125-02-99 and TAE 125-02-114 reciprocating engines. This AD requires removal of each high-pressure (HP) fuel pump before 300 flight hours (FHs) in service or within 55 FHs after the effective date of the AD, whichever occurs later. This AD was prompted by in-flight shutdowns on airplanes with TAE 125-02 engines. We are issuing this AD to prevent failure of the HP fuel pump, which could result in damage to the engine and damage to the airplane.

SAIB: CE-15-01

This Special Airworthiness Information Bulletin is being issued to alert operators and maintenance personnel of an airworthiness concern, specifically possible induced heading errors in systems using magnetic sensitive sensors such as magnetometers to provide heading information.
At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.

SAIB: CE-12-02R1

This Special Airworthiness Information Bulletin (SAIB) is written to inform the public about an approved alternative method of compliance (AMOC) to an airworthiness directive (AD) and how to obtain a copy of the Cessna global AMOC (aka; AMOC of general applicability) to AD 2001-06-07 against 1996 and after Cessna Models 172R and 172S airplanes
We have revised this SAIB to include the attached Cessna global AMOC to AD 2001-06-17, dated August 13, 2014.

SAIB: NE-11-56R1

This Revised Special Airworthiness Information Bulletin (SAIB) advises aircraft operators, Fixed Base Operators (FBOs), FAA repair stations and FSDOs, and Foreign Civil Aviation Authorities that jet fuel made from synthesized isoparaffins (SIP), hydroprocessed fatty acid esters and fatty acids (HEFA) or Fischer Tropsch (FT) synthetic blending components that meets the requirements of ASTM International Standard D7566 are acceptable for use on aircraft and engines certificated for operation with D1655 Jet A or Jet A-1 jet fuel, provided that they are re-identified as D1655 fuel. When re-identified as D1655 fuel, D7566 jet fuel meets all the specification requirements of D1655 and therefore meets the approved operating limitations for aircraft and engines certificated to operate with D1655 fuel, unless otherwise prohibited by the engine or aircraft type certificate (TC) holder. This SAIB is being revised to add SIP as a synthetic blending component that conforms to ASTM International Standard D7566.

AD 2015-07-03

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Model 402C and 414A airplanes. This AD requires repetitively inspecting the engine mount beams for cracks and contacting Cessna for FAA-approved corrective action if cracks are found. This AD also requires sending an inspection report to the FAA and to Cessna. This AD was prompted by reports of cracks found across the engine mount beams. We are issuing this AD to correct the unsafe condition on these products.

AD 2015-08-07

We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) oxygen mask regulators. This AD was prompted by a report of a malfunctioning mask having an inflatable harness with a high premature rupture rate due to defective silicon. This AD requires inspecting and replacing defective harnesses with new or modified serviceable units. We are issuing this AD to detect and correct defective harnesses, which could lead, in case of a sudden depressurization event, to a harness rupture, thereby providing inadequate protection against hypoxia and possibly resulting in unconsciousness of the affected flightcrew member and consequent reduced control of the airplane.

The 37th Annual General Aviation and Part 135 Activity Survey

The 37th annual General Aviation and Part 135 Activity Survey (GA Survey) for reporting on calendar year 2014 is underway!

Your participation is important!

-We need to hear from everyone who receives an invitation to complete a survey to prepare accurate statistics on aviation activity. The GA Survey is a scientific sample of
aircraft from the Civil Aviation Registry. Your responses are important because they represent many other aircraft like yours.

-Please respond, even if you did not fly your aircraft during 2014, you sold it, or the aircraft was damaged. These aircraft are just as important to calculate accurate
statistics.

-The GA Survey is the FAA's primary source of information about the size and activity of the general aviation and on-demand Part 135 fleet. Previous years' survey results can be found at

http://www.faa.gov/data_research/aviation_data_statistics/general_aviation/.

A wide range of aircraft, aircraft operations, and types of ownership are included in this survey. If you receive a survey, please complete it so that we have accurate data on...

-All types of aircraft—fixed-wing piston, turboprops, rotorcraft, turbojets, gliders, hot air balloons, amateur-built, light-sport aircraft, experimental and non-experimental aircraft.

-Many different aircraft operations, including:

-General operating and flight rules (Part 91)

-On-demand Part 135 (air taxi, air tours, and non-scheduled commuter)

-Agricultural aircraft operations (Part 137)

-Aircraft owned/operated by individuals and by companies as well as:

-Flying clubs, flight schools, fractional ownership programs

-Government agencies (Federal, state, local)

-N-Numbered military aircraft used for civilian purposes

Please be assured...

-Your responses are confidential. The information will be used only for statistical purposes and will not be released in any form that would reveal an individual participant.
Tetra Tech is an independent research firm that conducts the GA Survey on behalf of the FAA.

-You can contact Tetra Tech with questions toll-free at 1-800-826-1797 or email . Thank you!
