Narrative:

Upon contact with har approach, we were given clearance for approach via har transition to join the ILS 13 to mdt. We advised the controller that our commercial chart for ILS 13 to mdt. Did not include a transition from the har VOR. The controller advised us that his NOAA chart had this transition published. His chart showed amendment 9 and so did our chart, but both revision dates on the charts differed. The controller then gave us a clearance to fly a 120 degree heading after passing the har VOR to join the localizer 13 and to descend to 4000', and when established on the localizer for runway 13, we were cleared for the straight in ILS 13 approach to mdt. We were also advised that the terminal radar for mdt was inoperative. The approach and landing were completed with incident. Callback conversation with commercial chart supplier, to discuss difference between NOAA and commercial chart for har ILS runway 13 approach, revealed the following: there are 2 apparent differences, the first being the transition from the har VORTAC to the enola LOM, and the second being the missed approach procedure. The contact at the commercial chart company referred to the latest fdc NOTAM, which indicates that the transition is not available. The NOTAM also outlines the missed approach procedure, which is in agreement with the commercial chart procedure, and at variance with the NOAA published procedure. Another discussion between ASRS staff and NOAA staff indicates that the NOAA staff feel they have the current information. Examination of the fdc NOTAM publication indicates the possibility that they do not.

Title: ACR MLG FO WRITES THAT TRANSITION FROM HAR VOR TO APCH FOR ILS RWY 13 AT HAR AS INDICATED ON THE NOAA CHART IS MISSING ON COMMERCIAL CHART.

Narrative: UPON CONTACT WITH HAR APCH, WE WERE GIVEN CLRNC FOR APCH VIA HAR TRANSITION TO JOIN THE ILS 13 TO MDT. WE ADVISED THE CTLR THAT OUR COMMERCIAL CHART FOR ILS 13 TO MDT. DID NOT INCLUDE A TRANSITION FROM THE HAR VOR. THE CTLR ADVISED US THAT HIS NOAA CHART HAD THIS TRANSITION PUBLISHED. HIS CHART SHOWED AMENDMENT 9 AND SO DID OUR CHART, BUT BOTH REVISION DATES ON THE CHARTS DIFFERED. THE CTLR THEN GAVE US A CLRNC TO FLY A 120 DEG HDG AFTER PASSING THE HAR VOR TO JOIN THE LOC 13 AND TO DSND TO 4000', AND WHEN ESTABLISHED ON THE LOC FOR RWY 13, WE WERE CLRED FOR THE STRAIGHT IN ILS 13 APCH TO MDT. WE WERE ALSO ADVISED THAT THE TERMINAL RADAR FOR MDT WAS INOP. THE APCH AND LNDG WERE COMPLETED WITH INCIDENT. CALLBACK CONVERSATION WITH COMMERCIAL CHART SUPPLIER, TO DISCUSS DIFFERENCE BTWN NOAA AND COMMERCIAL CHART FOR HAR ILS RWY 13 APCH, REVEALED THE FOLLOWING: THERE ARE 2 APPARENT DIFFERENCES, THE FIRST BEING THE TRANSITION FROM THE HAR VORTAC TO THE ENOLA LOM, AND THE SECOND BEING THE MISSED APCH PROC. THE CONTACT AT THE COMMERCIAL CHART COMPANY REFERRED TO THE LATEST FDC NOTAM, WHICH INDICATES THAT THE TRANSITION IS NOT AVAILABLE. THE NOTAM ALSO OUTLINES THE MISSED APCH PROC, WHICH IS IN AGREEMENT WITH THE COMMERCIAL CHART PROC, AND AT VARIANCE WITH THE NOAA PUBLISHED PROC. ANOTHER DISCUSSION BTWN ASRS STAFF AND NOAA STAFF INDICATES THAT THE NOAA STAFF FEEL THEY HAVE THE CURRENT INFO. EXAMINATION OF THE FDC NOTAM PUBLICATION INDICATES THE POSSIBILITY THAT THEY DO NOT.
