Not arguing Keepitup
First Flight Yes but some folk took date of fitment so as to keep the paperwork simple.
Must be honest and say I never understood the limitation being from when the TT Straps where fitted, date of construction seemed more relevant to me.
For folk who are not familiar a Strap is Two hollow Pins, say 10 inches apart, joined by a single 'Strand' of wire,
The single strand goes around the two Pins, Thousands/Tens of thousands times in a continuous 'Loop' and so provides the strength to resist the Massive Forces generated by the rotating Main rotor head.
The Wire is coated in a Flexible Plastic material and is well protected.
I never saw the coating broke on any I removed.
I have always suspected corrosion at time of Manufacture.
But just my opinion.
