MMUN closed due Lear 45 crash
Just heard that a Lear 45 made a gear up landing this morning in Cancun MMUN/CUN. ?
Anyone heard any more on this, if its a 45 why was it still flying and is the problem related to the recent AD grounding... |
I believe that in the US the FAA has recently issued two ADs having to do with the 45. One was for the gear and isn't effective until August 27. The other for the HSAA was effective on August 13 but allowed three days for a ferry flight to get the airplane to a place where the work could be done. Further, I don't believe (but I'm not certain on this one) that all 45s needed the part replaced. The original (April 2003) AD which mandated replacement of the HSAA didn't apply to ALL 45s, and the new AD only applies to those 45s which had their HSAA replaced under the earlier AD (and again, I'm not sure that this is the case).
Did I misunderstand the ADs? Somebody throw me a bone here. Also, where was the A/C registered? Dave |

FLIGHT LIMITS (b) Non-revenue flights are permitted within 3 days after the effective date of this AD only for the purpose of positioning the airplane to a location where the replacement required by paragraph (a) of this AD can be accomplished. PARTS INSTALLATION (c) As of the effective date of this AD, no person may install an HSAA, P/N 6627401000-005, on any airplane. ALTERNATIVE METHODS OF COMPLIANCE (d) In accordance with 14 CFR 39.19, the Manager, Wichita Aircraft Certification Office (ACO), FAA, is authorized to approve alternative methods of compliance for this AD.

:( Oh this is very true
" August 14, 2003 From the editors of Aviation International News Subscribe | Feedback | Bizav Web Directory | Calendar | Advertise | www.ainonline.com Breaking Stories -------------------------------------------------------------------------------- Learjet 45 Fleet Grounded Until Fix Is Made An AD issued yesterday has effectively grounded the U.S.-registered fleet of 175 Bombardier Learjet 45s (and about 11 others in the UK, as a result of a similar AD by the CAA). AD 2003-16-19 stems from an incident last March in Australia in which a Learjet 45 experienced “severe vibration followed by a rapid nose-down pitch change.” The crew was able to maintain control of the aircraft and land safety. The ensuing investigation determined the incident was due to failure of the horizontal stabilizer actuator jackscrew and resulted in an April 11 AD requiring the replacement of part number T/N6627401000-001 with newly approved -005. But the FAA has decided that while P/N-005 is an improvement over P/N-001, the new part “was not manufactured per the type design data. A brittle fracture could occur. We determined that the configuration and quality controls over the production of these parts were so deficient that we do not have confidence that the airplane can be operated safely for any period of time.” The part is manufactured by MPC Products of Skokie, Ill. Owners have until this Saturday to fly the aircraft to a maintenance facility of their choice. According to a Learjet spokesman, the company has faith in P/N-005 and is working with the FAA to prove it will do the job. Bombardier is also working with the FAA on the certification of a new part should approval of P/N-005 not be granted. In either case, the certification process is not expected to conclude until the end of the month, after which replacement parts will start to be shipped. In the interim, supplemental lift will be provided by Skyjet, Bombardier’s air charter operation. :\ Australia-I believe- has grounded all of their 45's TFN:ouch: |
What about the Cancun incident/accident? Was that true or a rumour?
