B727 Maximum Turn Rate
In many of the B727 logbooks on the aircraft at work I see an entry "Exceeded Maximum Turn Rate." What does this mean, what are the possible effects, and what is done by maintenance to ensure no damage was done?

RE: B727 Maximum Turn Rate
Just a slight correction to the above topic....It should read "Exceeded Maximum Quick Turn Rate."
RE: B727 Maximum Turn Rate
Those 727's can roll really quickly, saw a pilot do it here on a farewell flight for 727's not sure if he had pax on board
RE: B727 Maximum Turn Rate
Flight crews are supposed to report any time the aircraft has been subjected to excessive loads; hard or overweight landings, high G-loads (like fast turns or pull-ups), tail strikes, etc.
Maintenance personnel conduct special inspections of the aircraft according to the manufacturer's criteria and the operator's policies. Depending on the type of excessive load, these inspections can be quite extensive and will often require various nondestructive testing (NDT) like eddy current, x-ray, or other types of specialized procedures. These inspections look for cracks, deformations or other types of damage.
Since the types of excessive loading, models of aircraft, and inspection requirements are many, it is not practical to list them here, but some rough examples can be given. Areas of the aircraft that would be subjected to concentrations of stress are of particular concern such as wing, vertical and horizontal stabilizer attachment points, pylons and fittings, landing gear and trunnions, fuselage skin, and primary load-bearing structure of the fuselage such as key stringers/longerons, floor beams, fuselage frames, etc.
Hope this helps.

I think what this entry is refering to is a minimum brake cooling time is required before the next blockout. The commonality at which it is written up shows me that it is not an actual maintenance problem but an operational adherence. At Fedex the verbage reads "44 minute brake cooling required by APLC (airport laptop computer). Block in time XXXXzulu.
