Spacepod - I'm in Irvington (west of Liberty Airport), so I don't have a good view of the Hudson from here.
Flytoo - That's classic!
I pulled up the following bulletin regarding prop strikes (all of this type of information is available via the internet).
The bulletin reads as follows:
"On numerous occasions, Textron Lycoming has been consulted about recommendations on whether to continue using an aircraft engine that has been involved in the separation of the propeller/rotor blade from the hub, the loss of a propeller/rotor blade tip or sudden stoppage following accidental propeller/rotor damage (such as propeller/rotor strike).
Conditions which surround accidents are many and varied; therefore the circumstances of the accident can not, in our opinion, be used to predict the extent of the damage to the engine or assure its future reliability.
Textron Lycoming must take the position that in the case of a sudden stoppage, propeller/rotor strike or loss of propeller/ rotor blade or tip, the safest procedure is to remove and disassemble the engine and completely inspect the reciprocating and rotating parts including crankshaft gear and dowel parts.
Any decision to operate an engine which was involved in a sudden stoppage, propeller/rotor strike or loss of propeller/rotor blade or tip without such an inspection must be the responsibility of the agency returning the aircraft to service.
Even tip damage is considered cause for teardown 
Lycoming's Service Bulletin 475B requires that in the event that the engine has experienced a propeller strike, inspection and possible rework of the accessory gear train as well as the rear of the engine's crankshaft is required.
Compliance with this service bulletin is mandatory per AD 91-14-22. 
The AD specifies the inspection at each engine overhaul, after a propeller strike, sudden stoppage, or whenever gear train repair is required. Lycoming's new SB seems to generalize the term propeller strike and sudden stoppage to be quite inclusive."
Be careful out there, and check those maintenance records!
