Narrative:

Runway 24 at pwk. Due to crosswind condition and high rate of descent characteristic of landing my airplane, I landed approximately on the displaced threshold line. This line has been moved in the past, yielding a shorter effective runway length (without change of construction of paved surface) due to growth of trees on the approach end. I suggest re-evaluating the threshold location. This runway is used primarily for small aircraft as a threshold location to allow for a longer landing distance prior to crossing the hump at runway 16 (intersection) would be a good thing. Callback conversation with reporter revealed the following information: the reporter stated that the trees are a problem in 2 ways. First, they are always getting higher. Second, they are part of a forest preserve so any attempts to trim or cut them are usually met with some resistance. According to the reporter, there have been no incidents or overruns that he knows of as yet. Reporter was advised to attempt to solve the issue on a local level. He will try to get some level of assistance from the airport manager, the national aircraft association that he belongs to and the local association of citabria owners. He will file another report if there are any further issues evolving from this situation.

Title: A CITABRIA PVT PLT RPT ON THE DIFFICULTY ENCOUNTERED WHEN LNDG RWY 24 DUE TO THE EVER INCREASING DISPLACED THRESHOLD BECAUSE OF THE HIGH TREES ON THE APCH END AT PWK, IL.

Narrative: RWY 24 AT PWK. DUE TO XWIND CONDITION AND HIGH RATE OF DSCNT CHARACTERISTIC OF LNDG MY AIRPLANE, I LANDED APPROX ON THE DISPLACED THRESHOLD LINE. THIS LINE HAS BEEN MOVED IN THE PAST, YIELDING A SHORTER EFFECTIVE RWY LENGTH (WITHOUT CHANGE OF CONSTRUCTION OF PAVED SURFACE) DUE TO GROWTH OF TREES ON THE APCH END. I SUGGEST RE-EVALUATING THE THRESHOLD LOCATION. THIS RWY IS USED PRIMARILY FOR SMALL ACFT AS A THRESHOLD LOCATION TO ALLOW FOR A LONGER LNDG DISTANCE PRIOR TO XING THE HUMP AT RWY 16 (INTXN) WOULD BE A GOOD THING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE TREES ARE A PROB IN 2 WAYS. FIRST, THEY ARE ALWAYS GETTING HIGHER. SECOND, THEY ARE PART OF A FOREST PRESERVE SO ANY ATTEMPTS TO TRIM OR CUT THEM ARE USUALLY MET WITH SOME RESISTANCE. ACCORDING TO THE RPTR, THERE HAVE BEEN NO INCIDENTS OR OVERRUNS THAT HE KNOWS OF AS YET. RPTR WAS ADVISED TO ATTEMPT TO SOLVE THE ISSUE ON A LCL LEVEL. HE WILL TRY TO GET SOME LEVEL OF ASSISTANCE FROM THE ARPT MGR, THE NATL ACFT ASSOCIATION THAT HE BELONGS TO AND THE LCL ASSOCIATION OF CITABRIA OWNERS. HE WILL FILE ANOTHER RPT IF THERE ARE ANY FURTHER ISSUES EVOLVING FROM THIS SIT.
