Apparently according to that news cutting:
"Honeywell are currently working with their Authorised Service Bulletins to ensure availability of inspection and repair capability ........"
If you're going to use this method of broadcasting, please do it properly!

Sorry Mr. Vulture
For your reference here is the original Emergency AD.
Hope this keeps the broadcasting police a little bit more appeased.

FAA
Aviation Safety
EMERGENCY
AIRWORTHINESS DIRECTIVE
Aircraft Safety Alerts
DATE: June 10, 2014
AD #: 2014-12-52
Emergency airworthiness directive (AD) 2014-12-52 is sent to owners and operators of
Honeywell International Inc. (Type Certificate previously held by AlliedSignal Inc., Garrett Turbine
Engine Company) TFE731-4, -4R, -5AR, -5BR, -5R, -20R, -20AR, -20BR, -40, -40AR, -
40R, -40BR, -50R, and -60 turbofan engines.
Background
This emergency AD was prompted by reports of 2nd stage low-pressure turbine (LPT2) blade
separations. Analysis indicates the presence of casting anomalies at or near the root of the LPT2
blade. This condition, if not corrected, could result in LPT2 blade failure, multiple engine in-flight
shutdowns, and damage to the airplane.
Relevant Service Information
We reviewed Honeywell Alert Service Bulletins (ASB) No. TFE731-72-A3792, dated June 5,
2014, ASB No. TFE731-72-A5242, dated June 5, 2014 and ASB No. TFE731-72-A5243, dated June
5, 2014. The service information describes procedures for identifying affected engines and follow-on
actions.
FAA’s Determination
We are issuing this AD because we evaluated all the relevant information and determined the
unsafe condition described previously is likely to exist or develop in other products of the same type
design.
AD Requirements
This AD requires before further flight a review of the engine log book maintenance records to
determine if any affected engines are installed.
This AD prohibits operation of an airplane with two or more affected engines that have LPT2
blades with less than 250 operating hours since new after receipt of this emergency AD.
Differences Between This AD and the Service Information
None.
Interim Action
We consider this AD to be an interim action. We anticipate that further AD action will follow.

Authority for this Rulemaking
Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation
safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more detail the scope of the Agency’s authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A,
Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA
with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices,
methods, and procedures the Administrator finds necessary for safety in air commerce. This
regulation is within the scope of that authority because it addresses an unsafe condition that is likely
to exist or develop on products identified in this rulemaking action.
Presentation of the Actual AD
We are issuing this AD under 49 U.S.C. Section 44701 according to the authority delegated to
me by the Administrator.
2014-12-52 Honeywell International Inc (Type Certificate previously held by AlliedSignal Inc.,
Garrett Turbine Engine Company): Directorate Identifier 2014-NE-09-AD.
(a) Effective Date
This Emergency AD is effective upon receipt.

blades, part number (P/N) 3075424-1, -2, or -3 installed.
(d) Unsafe Condition
This AD was prompted by reports of LPT2 blade separations. Analysis indicates the presence
of casting anomalies at or near the root of the LPT2 blade. We are issuing this AD to prevent LPT2
blade failure, multiple engine in-flight shutdowns, and damage to the airplane.
(e) Compliance
Comply with this AD within the compliance times specified, unless already done. Upon
receipt of this AD:
(1) Before further flight, review engine log book maintenance records to determine if any
LPT2 blade P/N 3075424-1, -2, or -3 with less than 250 operating hours since new are installed in an
engine.
(2) For two-engine airplanes that have two engines with LPT2 blades installed that have less
than 250 operating hours since new, remove all affected engines before further flight.
3
(3) For three-engine airplanes that have two or more engines with LPT2 blades installed that
have less than 250 operating hours since new, remove all affected engines before further flight.
(4) After the effective date of this AD, do not approve for return to service any engine with
LPT2 blades, P/N 3075424-1, -2, or -3 installed that has less than 250 operating hours since new.
(f) Special Flight Permit
Special flight permits are permitted for one over-land ferry flight to a maintenance facility
where an engine can be removed.
(g) Alternative Methods of Compliance (AMOCs)
The Manager, Los Angeles Aircraft Certification Office, FAA, may approve AMOCs for this
AD. Use the procedures found in 14 CFR 39.19 to make your request.

I'm assuming you've all seen the latest Honeywell SB's where the magic figure of clear above 130hrs is issued but the SB does have contradictions
We'll wait for the next FAA AD/AMOC is issued today or tomorrow.
FAA AMOC issued today Saturday
M.E
