Abstract : Since the introduction of the F-16 weapon system in the RNLAF, load monitoring has been carried out with a Mechanical Strain Recorder (MSR) in each aircraft and a Flight Loads Recorder (FLR) in one sixth of the fleet. From 1990 on, these recorders have been replaced by instrumentation which is capable of recording peaks and troughs in the signal of a strain gage at the location of the MSR. This new instrumentation has been installed in three aircraft per squadron. The result is a calculated severity per mission type per squadron. By using the mission type mixture, the severity per base, squadron or tail number can be established. Inspection schemes, based on the recently developed Fleet Structural Maintenance Plan for the RNLAF, can be changed accordingly. Mission type and take off configuration for each flight is available from the debriefing form. Besides the single channel measurements, supporting measurements with more channels have been carried out. In this way it was checked whether the load severity for the MSR location can be used for other structural locations.
