Helicopter main rotor smoothing is a maintenance procedure that is routinely performed to minimize destructive airframe vibrations induced by non-uniform mass and/or aerodynamic distributions in the main rotor system.
If the previously described time-based attack occurs when evaluating the QoS for the first time, the MR-BS may temporarily adopt the estimated values (i.e., which are worse than the values that would be estimated if the RS was not malicious) and then trigger a maintenance procedure that will be handled by the operator's control center.
No person or persons shall be liable for a violation of the provisions of subsection (c)(4)(A) if such person or persons proves by a preponderance of the evidence that such violation was not intentional and resulted from a bona fide error notwithstanding maintenance of procedures that are reasonably adapted to avoid such error.
In the case of that accident as I recall it, the concern was that there was some sort of a fatigue or maintenance procedure issue that could appear on that fleet of airplanes no matter who operated them.
On 26 June, NSB stated that in April they had discovered that not checking the whole axle was a weakness in the maintenance procedures, but that despite this, no new examinations had been done.
Jane Garvey, the administrator of the agency, said in an interview on CNN this morning, "Obviously, in light of the accident, we're taking a very, very careful look with the N.T.S.B. at the maintenance records, at the procedures that they have in place".
The feasibility of the GEMM-ESC production approach depends on reliable procedures and robust quality controls, including (i) ESC culture procedures that guarantee maintenance of pluripotency; (ii) monitoring of the genomic stability of ESCs; (iii) procedures for routine production of chimeras with a major contribution of the GEMM-ESCs to different tissues.
Since estrogen effects are modulated through estrogen receptors, variations in the ESR could have an important influence on its related procedures that provide pregnancy maintenance [ 15].
But longtime workers said that staffing and maintenance procedures were pared back and that redundancies that provided an extra margin of safety were eliminated.
Mr. Kelly made public a list of veteran aviation safety specialists the company had hired recently, among 70 new maintenance and engineering employees, and described new procedures that were being followed before planes were released to carry passengers.
