Flying Club Prop Strikes

My flying club has had two prop strikes in two weeks recently, both in a Beech Duchess, leaving only one of our three twin-engineed planes in service. I don’t have any of the details other than one occurred at Oshkosh and the other locally at Montgomery Field. I expected both to appear in the NTSB accident database but so far I don’t see anything. I don’t know anything about these planes so I don’t know whether they have awkward landing characteristics (like the Cardinal) or if its just an unlucky coincidence. Either way, its a club rule that you have to write about your event in the club newsletter so all will possibly be revealed later in the year.
