All our USA TAG owner's have received this information prior to the publication of the ASRA Safety Directive and are aware!
The text of the SD reviews the new information & observations that provide more information on the likely cause of the tragic accident in Western Australia!:rip:
The rotor serial number's identified as needing a close examination and possible modification will fall between # TAG 020 and TAG 089
Our two earliest and 2 latest machines ...appear to fall outside the non-spec rotor serial numbers. All the rest we are identifying the rotor by serial number & inspecting …. mods will be done and each machine will be released back to service ...per ASRA recommendations.
It appears that the rotor manufacturer … deviated from TAG Aviation material & design specs against Neil's expressed concerns that a smooth steel rod (vs the encapsulated bag of leadshot)… breaking away from the binding material & subject to large centrifugal forces ...departing the rotor by punching out the end cap! This deficiency for NOT following the designers requested mods to steel rods -IF such rods utilized…. rests on the rotor manufacture's shoulders!
If ANY gyro pilot of ANY TYPE feels a severe abnormal vibration … out-of-balance shakes in their rotor system … PLEASE LAND ASAP … & DO NOT continue flying a machine that is "talking" to you that something is NOT RIGHT !( In the WA TAG accident… deteriorating rotor performance signs were missed/ignored ...not treated seriously) & possible careful preflight checks may catch something that is failing!
I'm sure this will stir up a whole new hornets nest of "not-so-civil" dialogue & word-smith nit picking & speculation here! .
.YEP ...'ere-we GO AGAIN!!!:der::argue::violin:
As I have stated before … LET the ASRA expert gyro accident investigation team work it's way through the mass of material … we have to be patient … this all takes time & new facts come to light via Coroner's report releases and additional information from witnesses!
At this point the maker's of derogatory remarks about TAG gyro's material "made-in-China" , titanium & the fold mast plates design ...may soon be eating rancid crow … the failure of the plates appears to be secondary ...NOT THE PRIMARY CAUSE in these accidents!
TAG Aviation … manufacture of Titanium Explorer gyroplanes & TAGNA … the North American promotion, marketing & distributor believe in full disclosure of all safety issues that arise over time-in-service and in providing the best customer support & service out there!
Responses … be civil & I will respond … if it goes the way of much of the forum threads these days ...I'm gone!:whip:
