  We consider $e e q q$ contact interactions as a possible origin of an excess
of events above Standard Model predictions in $e^+ p \to e^+ jet$ at high $Q^2$
observed by the H1 and ZEUS collaborations at HERA. The HERA data prefer
chirality RL or LR contact terms and atomic physics parity violation
measurements severely limit parity-odd contact terms. With equal left-right and
right-left chirality interactions at an effective scale of order 3 TeV we are
able to reproduce the main features of the HERA data and still be consistent
with Drell-Yan pair production at the Tevatron and hadron production at LEP 2
and TRISTAN.
