NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: EVALUATE THE DESIGN OF CRANKCASE BREATHER LINE INSTALLATIONS OF ALL PIPER MODEL 28 AIRPLANES AND PIPER MODELS WITH SIMILAR ENGINE INSTALLATIONS TO DETERMINE THE NEED TO PROVIDE ICING PROTECTION ON CRANKCASE BREATHER TUBES FOR COLD WEATHER OPERATIONS, AND TAKE APPROPRIATE ACTION TO INTITIATE A RETROFIT OF THOSE MODELS OF AIRPLANES THAT NEED SUCH PROTECTION.
In plain language (FlightFinder summary)
The NTSB asks the FAA to evaluate the design of crankcase breather line installations on Piper Model 28 airplanes and other Piper models with similar engine installations, in order to determine whether icing protection is needed on the crankcase breather tubes for cold-weather operations. If such protection is deemed necessary, the FAA should initiate a retrofit of those affected airplane models.
