What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) CE-560, N560G, s/n 560-0112, operating under 14 CFR part 91 VFR flight rules, overshot runway 35 at kphl, and entered the grassy overrun beyond runway 35. The aircraft came to rest approximately 100 feet beyond the runway in the grassy overrun. The flight was a repositioning flight following a 14 CFR part 135 flight conducted by hortmont aviation services, air carrier certificate number CDMA769C. The SIC stated, "the weather was good (10 miles visibility), VFR with approximately a 5 knot tailwind. For arriving traffic on runway 27 we were asked to keep the approach in close. When turning final we were slightly high and approximately 20 knots fast, but appeared to be well within safety margins. On landing the aircraft floated due to excessive speed and the light tailwind. I advised the captain to get the aircraft on the ground. Once we touched down the captain applied brakes and reverse. After a short period of time he eased off the brakes and put the reverse at idle. I called out max brakes and reverse at which time I also got on the brakes." The only damage to the aircraft were the main tires, which were flat-spotted due to the use of the braking system.
